merge with stable
The change from
7b627923739f (parent 2) is not needed after switching
to the new url parser.
rename path_auditor to pathauditor
The Mercurial 1.9 release is moving a lot of stuff around anyway and we are
already moving path_auditor from util.py to scmutil.py for that release.
So this seems like a good opportunity to do such a rename. It also strengthens
the current project policy to avoid underbars in names.
