[PATCH] gitweb: correctly store previous rev in javascript-actions mode

[Jonathan Nieder <jrnieder@gmail.com>]

From: Robert Luberda <robert@debian.org>

Without this change, the setting

 $feature{'javascript-actions'}{'default'} = [1];

in gitweb.conf breaks gitweb's blame page: clicking on line numbers
displayed in the second column on the page has no effect.

For comparison, with javascript-actions disabled, clicking on line
numbers loads the previous version of the line.

Addresses https://bugs.debian.org/741883.

Hi Robert,

Years ago, you sent this obviously correct patch to the link mentioned
above, but it got lost in the noise.  Sorry about that.  Hopefully
late is better than never.

May we forge your sign-off?  See
https://www.kernel.org/pub/software/scm/git/docs/SubmittingPatches.html#sign-off
for more details about what this means.

Jakub et al, any thoughts?  I don't see any unit tests in gitweb/static
that could avoid this regressing --- am I missing some, or if not any
hints for someone who would want to add a test framework?

Thanks,
Jonathan
