The page https://lilypond.org/doc/v2.23/Documentation/notation/writing-text.html#text-marks
is missing some backslashes in the box "Note: Older LilyPond used the [\]mark command ...". On the other hand, the corresponding PDF https://lilypond.org/doc/v2.23/Documentation/notation.pdf is fine. The corresponding Texinfo source is @warning{Older LilyPond versions used the @code{\mark} command for text marks, even though it is primarily intended for rehearsal marks (@pxref{Rehearsal marks}). The @code{\textMark} and [...] and the definition of @warning in macros.texi is @ifhtml @macro warning{TEXT} @html <div class="warning"> @end html @strong{Note:} \TEXT\ @c keep the space for proper nesting of </p> @html </div> @end html @end macro @end ifhtml @ifnothtml @macro warning{TEXT} @quotation @quotation @cartouche @b{Note:} \TEXT\ @end cartouche @end quotation @end quotation @end macro @end ifnothtml I don't immediately see what this discrepancy could be caused by, apart from a bug or limitation of texi2html 1.82. Can this be worked around somehow? Thanks, Jean
