Subject: [PATCH] vc-git.el: Take into account the destination name in
vc-checkout.
This is necessary for vc-version-other-window. Based on a patch by Sam
Vilain <sam.vilain@catalyst.net.nz>.
Currently, the vc-git-checkout function uses `git checkout' to fetch a
file from the git repository to the working copy. However, it is
completely ignoring the input argument that specifies the destination
file. `git-checkout' does not support specifying this, so we have to
use `git-cat-file', capture the output in a buffer and then save it.
