Fix accessing a repository via -R/--repository through a symlink. Sometimes the repository root was compared to os.getcwd(), which always uses the canonical path without symbolic links in it. This would changes self.root of the localrepo objects to always use os.sep as the directory separator, which is implicitly assumed in some places, but may not be the case if somebody uses -R foo/repo on windows.

Merge with upstream

localrepo: factor commit and rawcommit note: rawcommit with an empty text will now launch the editor

localrepo.commit: little cleanups - use a list for new fileids - sort the removed files

Clarify untracked file merge message
