Scheme mode paren higlighting bug?

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.4 (patch 4) "Artificial Intelligence" [Lucid] (i386-unknown-freebsd4.3) of Mon Jul 30 2001 on galibier configured using `configure --with-prefix=no --site-includes=/afs/informatik.uni-tuebingen.de/i386_fbsd32/include --site-libraries=/afs/informatik.uni-tuebingen.de/i386_fbsd32/lib --with-menubars=lucid --with-scrollbars=lucid --with-xpm --with-jpeg --with-png --with-dialogs=athena --with-widgets=athena --mail-locking=file --pdump' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: The following text in a Scheme mode buffer seems to confuse paren highlighting. The last parenthesis in the ELSE branch corresponds to the open parenthesis before LET, but XEmacs highlights the first parenthesis after LET. The "\" at the end of the line seems to be the source of confusion: It works if I write "; eat backslash" instead of "; eat \".
