-  {\MTversion{normal}\MTnonlettersobeymathxx$\mathbf-$\sffamily, when
-    `non-letters' are declared to obey math alphabets.}}
-
-\begin{framed}
-  \textbf{Important:} the package does \cs{MTnonlettersdonotobeymathxx} by
-  default. The reason is that activating the mechanism adds some constraints to
-  the way things must be input, adding
-  |\usepackage{mathastext}|{}\cs{MTnon\-letters\-obey\-mathxx} to a pre-existing
-  document might well create errors: 
-
-  All these characters treated by \mst, such
-  as |?|, |[|, |<| now represent (in math mode only!) \emph{two} `tokens' and
-  this will utterly confuse \TeX{} if some precautions are not taken: |$x^?$|,
-  |$R^+$| or |$\mathopen<A\mathclose>$| \emph{must} now be coded as |$x^{?}$|,
-  |$R^{+}$| and |$\mathopen{<}A\mathclose{>}$| (the rule is to do as if |?|,
-  |+|, |<| or |>| were each really \emph{two} characters).
-
-  Even if this rule is respected in the document source, it is still a
-  possibility that incompatibilities with other packages will arise because \mst
-  does a `mathematical activation' of the characters which could be unexpected
-  and unchecked for by other packages. This is precisely the case with the
-  |amsmath| package, and the problem goes away by just making sure that
-  |amsmath| is loaded before \mst{} (generally speaking, \mst should be loaded
-  last after all packages dealing with math things).
-\end{framed}
-
-The brace control sequences |\{| and |\}| have their own (supplementary) switch,
-which is (even) less activated by default. The reason is that after
-\csb{MTexplicitbracesobeymathxx}, they regrettably can not be used anymore as
-delimiters: |\big\{| or |\big\}| cease to function and must be replaced by
-|\big\lbrace| and |\big\rbrace|. But
-\MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTexplicitbracesobeymathxx we
-can now enjoy $\mathtt{\{a, a>b\}}$, $\mathbf{\{a, a>b\}}$, $\mathsf{\{a,
-  a>b\}}$, or even $\mathnormalbold{\{a, a>b\}}$.\footnote{this last example
-  uses the \cs{mathnormalbold} additional alphabet defined by \mst.}
-
-There is no such restriction with $($, $)$ or the brackets $[$, $]$. When used
-as delimiters though, they will become again unreactive to the math alphabets:
-the same applies to $<$ and $>$ or to any of the other characters such as the
-slashes $/$, $\backslash$, when they are used as delimiters. This is a rather
-obvious restriction except possibly for the smallest size delimiters (the
-so-called `small variants'), as all other sizes will be anyway absent from the
-text fonts. Even the small variants may not be really available in the text
-fonts: for example the standard $<$ used as a delimiter is in \LaTeX{} a
-\cs{langle}: $\langle$. With standard \LaTeX{} |$\left< x\right>$| gives
-$\langle x\rangle$.
-
-
-Actually, \mst does try to pick up most of the `small variants' in the text
-font: |$\left<x\right>$| gives $\left<x\right>$ (but |$\left<b\right>$| gives $\left<b\right>$.) If you don't like that use the
-option §nosmalldelims§ (it is indeed perhaps a bit strange to have $\left<
-  x\right>$ next to $\left< X\right>$, again before blaming me, consider using
-§nosmalldelims§.) At any rate, whether `small' or not, delimiters are not under
-the extended law of math alphabets, this is a general rule of the way \mst
-manages these things.
-
-Examples: |\mathbf{<a,b>}| gives $\mathbf{<a,b>}$. 
-|\mathbf{\left<a,b\right>}| gives $\mathbf{\left<a,b\right>}$. 
-|\mathbf{\mathopen{<}a,b \mathclose{>}}| gives $\mathbf{\mathopen{<} a,b
-  \mathclose{>}}$.
-The \LaTeX{} standard behavior for 
-|\mathbf{\mathopen{<}a,b\mathclose{>}}| is
-\endgroup

+  last after all packages dealing with math things).
+\end{framed}
+
+The brace control sequences |\{| and |\}| have their own (supplementary) switch,
+which is (even) less activated by default. The reason is that after
+\csb{MTexplicitbracesobeymathxx}, they regrettably can not be used anymore as
+delimiters: |\big\{| or |\big\}| cease to function and must be replaced by
+|\big\lbrace| and |\big\rbrace|. But
+\MTmathoperatorsobeymathxx\MTnonlettersobeymathxx\MTexplicitbracesobeymathxx we
+can now enjoy $\mathtt{\{a, a>b\}}$, $\mathbf{\{a, a>b\}}$, $\mathsf{\{a,
+  a>b\}}$, or even $\mathnormalbold{\{a, a>b\}}$.\footnote{this last example
+  uses the \cs{mathnormalbold} additional alphabet defined by \mst.}
+
+There is no such restriction with $($, $)$ or the brackets $[$, $]$. When used
+as delimiters though, they will become again unreactive to the math alphabets:
+the same applies to $<$ and $>$ or to any of the other characters such as the
+slashes $/$, $\backslash$, when they are used as delimiters. This is a rather
+obvious restriction except possibly for the smallest size delimiters (the
+so-called `small variants'), as all other sizes will be anyway absent from the
+text fonts. Even the small variants may not be really available in the text
+fonts: for example the standard $<$ used as a delimiter is in \LaTeX{} a
+\cs{langle}: $\langle$. With standard \LaTeX{} |$\left< x\right>$| gives
+$\langle x\rangle$.
+
+
+Actually, \mst does try to pick up most of the `small variants' in the text
+font: |$\left<x\right>$| gives $\left<x\right>$ (but |$\left<b\right>$| gives $\left<b\right>$.) If you don't like that use the
+option §nosmalldelims§ (it is indeed perhaps a bit strange to have $\left<
+  x\right>$ next to $\left< X\right>$, again before blaming me, consider using
+§nosmalldelims§.) At any rate, whether `small' or not, delimiters are not under
+the extended law of math alphabets, this is a general rule of the way \mst
+manages these things.
+
+Examples: |\mathbf{<a,b>}| gives $\mathbf{<a,b>}$. 
+|\mathbf{\left<a,b\right>}| gives $\mathbf{\left<a,b\right>}$. 
+|\mathbf{\mathopen{<}a,b \mathclose{>}}| gives $\mathbf{\mathopen{<} a,b
+  \mathclose{>}}$.
+The \LaTeX{} standard behavior for 
+|\mathbf{\mathopen{<}a,b\mathclose{>}}| is

+%   |1.3| [2013/09/02]: user level command to specify extra spaces in math mode

+%   skip to be inserted after; for example \cs{thickmuskip} or explicitely
+%   |0.1mu| or |0.1mu plus 0.1mu minus 0.1mu|.
+%
+%   For this, letters are made mathematically active. This is now the package
+%   default (version |1.2| did this only in the absence of option |italic|, or
+%   more precisely when the font used was not of shape |it| or |sl|). But if
+%   \cs{MTsetmathskips} has not been used for that letter, the only effect of
+%   the math activation is, as in |1.2|, to add the italic correction
+%   automatically, except when the font shape is detected to be |it| or |sl|; in
+%   these latter cases, although mathematically active, the letter acts in the
+%   standard way.
+%
+%   The command \cs{MTmathstandardletters} turns off math activation and its
+%   effects for all letters.
+%
+%   Ligatures within the argument of a math alphabet command are impeached by
