Hmm, I'm working on a different idea that happens to use the same
selector letter.  My idea is to have a more generic head (or rather,
'head-most') selector, which would work by placing 'h:' before any
selector.  It only works when selectors are used to get one or more
revisions, and simply does erase_ancestors() on the bunch of fetched
revision ids.

The benefit is that it's not just reserved to branches, but can be
used with other selectors, such as c: (in which I have a personal
interest).

A few usage examples:

monotone log -r h:a:graydon
monotone update -r h:c:x-levitte-tested=yes

bdowning> monotone: selected update target 
7b88f7c9b843cae0b068b5232edf812c9b2b367d

Honestly, I can't quite understand why an update to another branch
doesn't automatically imply the head of that branch...

Cheers,
Richard
