bug#19545: 24.4.51; VC doesn't support SMerge mode with Git back-end

[Eli Zaretskii]

When there's a merge conflict in a Bazaar repository, visiting a file
with conflict markers turns on SMerge mode automatically, and saving
the file after resolving the conflict automatically runs the bzr
command necessary to tell bzr the conflicts were resolved.

This doesn't happen in a Git repository.  I see that the necessary
code was added to master, so I guess I'm asking to backport that to
the release branch.
