bug#4307: 23.1; vc-annotate should run svn asynchronously

[Tom Tromey]

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:


I typed "C-x v g" (vc-annotate) in a buffer in a source tree managed by
svn.

I expected "svn annotate" to run asynchronously.  This is what happens
for CVS.  Instead, it ran sychronously.



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/share/emacs/23.1/etc/DEBUG for instructions.
