Make {rev} behave correctly for some corner cases.
The {rev} keyword now expands like so:
* To nothing, when the working directory has no parent (i.e. when
in a freshly init'ed repo or after running 'hg update null').
* To the revision number of the (first) parent of the working
directory otherwise.
