zsh: typo in commit completion

issue228: Fix repositories at the filesystem root (/ or C:\) Thanks to Robert Shaw and other people on the list for the suggestions.

Export changelog dict in localrepo.commit

tests: add -i switch Prompt to accept changes for tests where output changed

tests: add -R switch Restarts at first .err file if one exists, otherwise runs all tests

tests: sort test list if running all tests

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

Fix up parent display in logging For changesets with a first parent nullid, but not rev 0, we ought to display a null parent.

Clarify untracked file merge message

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