+%
+% \item[indentfirst]\SpecialOptIndex{indentfirst} An option that allows
+% to override \quo/'s indentation mechanism and to manually switch
+% on/off first-line indentation. The permitted values are \textsf{auto},
+% \textsf{true}, and \textsf{false}. The default value is
+% \textsf{auto}.\footnote{The \textsf{indentfirst} option may act as a
+% fallback solution for cases where \quo/'s indentation mechanism fails.
+% Currently, first lines will always be indented a)~immediately after
+% \texttt{\textbackslash begin\{document\}} b)~after a
+% \textsf{sloppypar}, \textsf{center}, \textsf{flushleft}, or
+% \textsf{flushright} environment. Thanks to Enrico Gregorio for
+% pointing out \quo/'s behaviour with respect to \textsf{sloppypar},
+% \textsf{center} \& friends.}
