vc-revert-buffer 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 21.2 (beta29) "Hestia" [Lucid] (sparc-sun-solaris2.6, Mule) of Thu Feb 17 2000 on betty configured using `configure --with-mule --with-clash-detection' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: This bug used to exist with GNU Emacs but was fixed about 1-2 years ago. I don't remember how it was fixed, but the bug also occurs in xemacs. Create the following directory setup: $ ls * dir1: RCS/ file1 dir2: file2 With file1 already checked in. Now run xemacs, and load the vc.el package. In one frame, open three windows with these buffers: file2 ------------ file2 ------------ file1 Go to the third window, checkout file1, edit the text, then save. Now do a vc-revert-buffer and say "yes" to cancel the changes. dir1/file1 does not change. However, a fresh copy is incorrectly stored in dir2/file1! I believe CVS has a similar problem.
