[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".

Warning: 

Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.

To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.

To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .
