[E-devel] [PATCH core/elementary] configure.ac: Fix rev to work outside of git tree too

[U. A. E. <ull...@in...>]

From: "U. Artie Eoff" <ull...@in...>

When configuring the source outside of the git tree
(i.e. git checkout-index ...), 'git rev-list --count HEAD'
will fail.  Thus, just set v_rev to 0 like we did when this
was an svn managed project.
