Dear Bug Team!
21.5.b28 has an annoying regression where it incorrectly sets the
buffer modified flag.
M-x shell
touch /tmp/blah
C-x f /tmp/blah
M-x shell
echo "change" >> /tmp/blah
C-x b blah
M-x revert-buffer
"yes"
The buffer "blah" is now marked as modified.
This is not reproducible under 21.5.b27.

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 .
