commit: note when files are missing
Before, you could experience the following strange interaction:
$ hg commit
nothing changed
$ hg merge
abort: outstanding uncommitted changes
which confused at least one user in #mercurial.
hg: make parseurl() consistently return normalised path
Before this the path was only normalised when a fragment was used.
bugzilla: more documentation formatting fixups
Correct typo in numbering list of access methods.
Convert a section reference and a template parameter reference into
literal text, for consistency with other use.
rebase: don't mark file as removed if missing in parent's manifest (
issue2725)
