Yep. It took a bit for the revset facility to be supported everywhere.
In fact, it seems we missed 'hg heads <X>' (though the slightly
different 'hg heads -r <X>' does work).

But revsets are extremely powerful and render most of log's other
options redundant (along with all the other commands that show
changesets). So for instance, you can do:

hg log -r 'heads(branch(111))'

..though it'd obviously Just Work if you used a less ambiguous branch
naming scheme.
