Start emacs -Q. Visit a CVS-controlled file. Then:
C-x v l
M->
C-x v l
Notice the CVS log added once more after current end of log buffer.
I tracked this down to the following snippet from `vc-do-command´:
(save-current-buffer
(unless (or (eq buffer t)
(and (stringp buffer)
(string= (buffer-name) buffer))
(eq buffer (current-buffer)))
(vc-setup-buffer buffer))
That is, `vc-setup-buffer´ (which erases the buffer) is *not* called if
the buffer where the VC command is to be executed in equals the current
buffer. I guess that logic has a reason, so it probably should be some
upper layer which should erase *vc-log-buffer*...
For git, for example, function `vc-git-print-log´ calls
`vc-setup-buffer´. Probably the other VC backends should follow suit?
If this is the way to go, I could provide patches for VC backends CVS
and RCS, pls let me know.
