Change the behavior so that the sender (the "From" header in the notification
mail) in case of the "changegroup" hook is the user that did the first commit
in the changegroup. The option is configurable, if you set "notify.fromauthor"
to "True" in your config, the new behavior is activated. If you do not set the
option, the behavior is as before. The commit adds to an existing test to show
various aspects of the changed behavior.
Globbing is usually used for filenames, so on windows it is reasonable and very
convenient that glob patterns accepts '\' or '/' when the pattern specifies
'/'.
If the working dir parent was destroyed by rollback, then the old
behaviour is perfectly reasonable: restore dirstate, branch, and
bookmarks. That way the working dir moves back to an existing
changeset rather than becoming an orphan.
But if the working dir parent was unaffected -- say, you updated to an
older changeset and then did rollback -- then it's silly to restore
dirstate and branch. So don't do that. Leave the status of the working
dir alone. (But always restore bookmarks, because that file refers to
changeset IDs that may have been destroyed.)
