bug#4685: 23.1; vc-rcs doesn't recognize status when checkin-switch -l

[Evangelos Evangelou <vangelis@email.unc.edu>]

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 bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

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

It seems that emacs doesn't recognize the vc-status of the file when I
set the variable vc-rcs-checkin-switches to "-l". The first time I
execute vc-next-action for checking in the file is checked in and then
checked out automatically because of the "-l" switch. The %% are not
present in the mode line. The second time I run vc-next-action it
attempts to run co instead of ci. On the other hand, running
vc-next-action through vc-dir doesn't seem to have a problem. I only
observed this in emacs 23; emacs 22 is also working as expected.

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
c:/emacs/etc/DEBUG for instructions.
