+% % Instead of specifying a firstline at which to start printing a range
+% of lines, you can define a start string; the start of the range is
+% the first line that exactly equals the string. (The comparison is made
+% before any characters are gobbled off the front of the line.) Similarly for a stop
+% string. You can mix line-numbers and strings, e.g.\ start at
+% firstline, and end at a stop string. Specifying the strings is a

+% FROM
+% Second verbatim line.

% The definition of \cs{FV@FindStartStop} changes, so that we don't
% have to check irrelevant conditions with each line.
%
+% Here's how it works; for simplicity we assume \texttt{firstline} and \texttt{lastline}
+% have been specified, rather than start or stop strings.
+%
+% The first time \cs{FV@FindStartStop} is called:
+% \begin{enumerate}
+% \item It calls
+% \cs{FV@DefineFindStart}. (The name roughly means "define\\
+% \cs{FV@FindStartStop} to detect when we've reached the \underline{start} of the
+% specified range".) This checks the range parameters that have been
+% specified, and then redefines \cs{FV@FindStartStop} (yes, the
+% function that has called this code) to contain only
+% the necessary checks, for efficiency reasons:
+%
+% \begin{itemize}
+%
+% \item If we haven't printed any lines yet, which is true when\\
+% \cs{FV@FindStartStop} is first called, we only need to check
+% the current line-number against \texttt{firstline}, so we redefine
+% \cs{FV@FindStartStop} to be\\
+% \cs{FV@FindStartNum}.
+%
+% \item If \texttt{firstline} isn't set, we only have to check the
+% current line-number against \texttt{lastline}, so we redefine
+% \cs{FV@FindStartStop} to be \cs{FV@DefineFindStop}.
+% (The name roughly means "define\\
+% \cs{FV@FindStartStop} to detect when we've reached the
+% \underline{stop} (end) of the
+% specified range", but unlike the START case, it includes code
+% (\cs{FV@@PreProcessLine}) to print the current line.)
+%
+% \end{itemize}
+%
+%
+% \item It then calls the newly-defined \cs{FV@FindStartStop} to see
+% if the current line being processed is within the range to be printed.
+%
+% \end{enumerate}
+%
+% \cs{FV@FindStartStop} is redefined once as described above, but it
+% can be redefined again:
+%
+% \begin{enumerate}
+%
+% \item When we have reached \texttt{firstline}, i.e.\ have entered the
+% range to be printed, we redefine
+% \cs{FV@FindStartStop} to be \cs{FV@DefineFindStop}. (We know
+% we've reached the start, so there's no point checking that again on
+% future calls.)
+%
+% \item When we reach \texttt{lastline} and have printed it, we won't
+% want to print any more lines, so we redefine
+% \cs{FV@FindStartStop} to \cs{relax} so we do nothing (and do
+% it efficiently).
+%
+% Note that when \texttt{firstline} = \texttt{lastline} (= 6, say), it is
+% \cs{FV@FindStartNum} (which \cs{FV@FindStartStop} has
+% initially been redefined to) that notices when we reach line
+% 6, and prints it, and redefines \cs{FV@FindStartStop} to be \cs{FV@DefineFindStop}.
+% Then we read line 7, so \cs{FV@DefineFindStop} has to check
+% whether we've passed \texttt{lastline}, and therefore shouldn't print
+% the current line, before
+% redefining \cs{FV@FindStartStop} to \cs{relax} as explained above.
+%
+% By contrast, when \texttt{firstline} is less than \texttt{lastline} (= 6, 8, say), when we
+% reach line 8, \cs{FV@DefineFindStop} sees that we're at the
+% end of the range, and \emph{does} print the line, before
+% redefining \cs{FV@FindStartStop} to \cs{relax} as above.
+%
+% This slight weirdness is because several of the macros are
+% defining themselves and one another, resulting in a slightly weird
+% execution flow.
