an alternative would be to handle this like hg does: as long as a
subcommand is a unique prefix, accept it as such, otherwise show
possible completions. This is very convenient for interactive use, and
if at some later point a new subcommand removes the uniqueness, users
will learn quickly enough ;-)
For scripting use, one should always use the full form anyway.
