[Monotone-devel] "monotone update" change

[Tom Tromey]

I've checked in the appended.

I'm sending it here since it isn't clear to me that this is the best
approach.  Perhaps it would be better to have pick_update_target
return a bool telling the update command what to do.

OTOH, perhaps this change sets the stage for making "rm NEWS; monotone
update" work.

I'm committing anyway since reverting seems cheap...  naturally I'm
being careful to keep each commit a single logical change.  If I'm
missing something here, let me know and I will revert.
