Subject: bug#901: [PATCH] 23.0.60; "l" in "annotation" buffer does nothing
Date: Fri, 05 Sep 2008 21:58:29 -0700

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 emacs-pretest-bug <at> gnu.org mailing list.

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

I visited a file that is in a git working tree, then typed C-x v g to
display annotations.  I put point at the beginning of some line in that
buffer, and typed "l".  I expected to see point move the the line in
*vc-change-log* whose commit matches that displayed in the *Annotate
... buffer, but instead it just stays on the second commit.

This patch fixes it for me.
