I'm confirming this bug with respect to the subcommands part.  Like Mark, I
have reservations regarding the possibilities of aliases.  In the case or
remove vs rm, I sort of wish I had gone with rm instead of remove in the
first place, but if DOS people start asking for a del alias for remove, I
think that's going a bit far.

On the other hand, having the *infrastructure* for aliases does sound like
a good idea, since it should allow us to keep the current commands for
backwards-compatibility while moving functionality around.  For example,
I'd like to have a query subcommand to view the contents of a patch, such
as query patch-summary -p foo, perhaps, which would be the same as the
current annotate -s -p foo.  Ideally, we could somehow share code between
the two, and enforce an identical interface.  Perhaps a better example
would be changes, which could potentially be moved wholesale into query.

So I guess I'm confirming both infrastructure improvements.
