subrepo: invoke "_sanitize()" also after "git merge --ff" Before this patch, sanitizing ".hg/hgrc" in git subrepo doesn't work, when the working directory is updated by "git merge --ff". "_sanitize()" is not invoked after checking target revision out into the working directory in this case, even though it is invoked indirectly via "checkout" (or "rawcheckout") in other cases. This patch invokes "_sanitize()" explicitly also after "git merge --ff" execution.
