Ahhh, yes, this clarifies things.  In my mind, revision selectors should
always be trying to find the single revision that meets your selection
criteria.  There might not be such a single match, and then they should
complain, and give you a list.

What we would like is two new things: a way to specify a testresult
selector (or possibly just a general purpose cert selector a'la
c:certname=certval) *and* a way to say "take the latest rev that
satisfies this selector."  The latest rev part might still be ambiguous
(multiple heads) but then it just give you the list of possibilities
like usual.  This could be implemented as a flag, or as an extension of
the selector syntax (capitalize the selector character?  add an 'l'
after it?)

So al:richard or A:richard or '--latest-selector a:richard' would be the
latest rev authored by richard, and rl:address@hidden would be the latest
revision with a true testresult cert signed by richard.

Does this make sense?

But as a separate issue, is there anything that we would want the
--cert=certname:certvalue flag that works like the --branch flag (in
fact, --branch would just be a special case, --cert=branch:branchname)
for?  Or am I just inventing useless features?
