[Bug: 21.5-b21] uncomment-region bug

Dear Bug Team! I start with xemacs -vanilla main.cpp where main.cpp does not yet exist. The modeline says "C++". I enter "// hello " (without the " signs). Mark the whole buffer with "C-x h" and enter "M-x uncomment-region" The result looks like this: "/ hello " I expect this: "hello " XEmacs version: "XEmacs 21.5 (beta21) \"corn\" (+CVS-20050720) [Lucid] (i386-suse-linux, Mule) of Tue Sep 13 2005 on macintyre" If you wish, I could give detailed decriptions for this bug in other modes (e.g. haskell, java, vhdl, ...). There is a discussion regarding this bug on comp.emacs.xemacs, called "uncomment does uncomment too much". ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux macintyre 2.6.12 #1 SMP Wed Mar 23 21:52:37 UTC 2005 i686 athlon i386 GNU/Linux ./configure 'i386-suse-linux' '--with-gcc' '--with-dynamic' '--enable-debug=no' '--enable-error-checking=none' '--with-cflags=-O2 -march=i586 -mtune=i686 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -Wall -Wno-switch -pipe -O2 -march=i586 -mtune=i686 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -fno-strict-aliasing' '--with-ldflags=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/X11R6/bin' '--datadir=/usr/share' '--with-archlibdir=/usr/lib/xemacs/21.5.21.20050721/i386-suse-linux' '--with-docdir=/usr/lib/xemacs/21.5.21.20050721/i386-suse-linux' '--with-lispdir=/usr/share/xemacs/21.5.21.20050721/lisp' '--with-etcdir=/usr/share/xemacs/21.5.21.20050721/etc' '--with-statedir=/var/lib/xemacs' '--with-moduledir=/usr/lib/xemacs/21.5.21.20050721/i386-suse-linux/modules' '--infodir=/usr/share/xemacs/info' '--mandir=/usr/share/man/man1' '--enable-database=gdbm,berkdb' '--with-ncurses' '--with-tty=yes' '--with-site-lisp' '--disable-mc-alloc' '--disable-kkcc' '--enable-sound=native' '--with-gpm' '--enable-pdump' '--disable-dump-in-exec' '--with-xpm' '--with-gif' '--with-tiff' '--with-jpeg' '--with-png' '--with-x' '--with-athena=3d' '--enable--menubars=lucid' '--enable-scrollbars=lucid' '--enable-dialogs=athena' '--enable-widgets=athena' '--x-includes=/usr/X11R6/include' '--x-libraries=/usr/X11R6/lib' '--enable-mule' '--with-xim=xlib' '--with-xfs' '--enable-clash-detection' '--with-ldap' '--with-pop' 'CFLAGS=-O2 -march=i586 -mtune=i686 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -Wall -Wno-switch -pipe -O2 -march=i586 -mtune=i686 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -fno-strict-aliasing' 'LDFLAGS=' 'build_alias=i386-suse-linux' 'host_alias=i386-suse-linux' 'target_alias=i386-suse-linux' XEmacs 21.5-b21 "corn" (+CVS-20050720) configured for `i386-suse-linux'.
