bug#4025: 23.1.50; VC shows bazaar files as modified on modeline

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the [email protected] mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When visiting a file which is versioned with bazaar, on a pristine
branch, the modeline indicates that it is locally modified (shows
Bzr:700). After M-x vc-revert, it shows its right state (Bzr-700)
and keeps doing so for subsequent emacs sessions.

One workaround is to execute `bzr revert` for the whole branch.

If there is a modified file, VC will keep showing it as locally modified
even after executing `bzr revert` on a shell and doing a M-x
revert-buffer.

Using bzr 1.17

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.1.50/etc/DEBUG for instructions.
