shelve: stop passing list of files to revert...

shelve: stop passing list of files to revert It seems to work just fine to not specify any files here. I suspect it looked the way it did for historical reasons. It apparently used to use merge instead of rebase until (shelve: use rebase instead of merge (issue4068), 2013-10-23) and it makes sense to want to restrict the set of files then. I noticed this because of the files.extend(shelvectx.p1().files()). If the working copy was clean before, then shelvectx.p1() will be the working copy parent and that ended up adding all the files in that set. In our Google-internal Mercurial setup (including a FUSE) that was very noticeably slow when the working copy parent happened to have many files in large directories. This patch doesn't yet remove the call to shelvectx.p1().files(). We also use that set for deciding what to back up. I'm pretty sure it's safe to back up only the set of files we already back even if we no longer restrict the set of files to revert, so this patch should be safe on its own. Regardless, the next patch will delegate the backing-up to cmdutil.revert(). Incidentally, this also gets rid of a repo.pathto() that I had earlier wanted to get rid of.
