No.

Learn to type "--decorate-refs="refs/heads/[m]aster", and not twewak
the code at all, perhaps.  The users of existing "with no globbing,
/* is appended" interface are already used to that way and they do
not have to learn a new and inconsistent interface.

After all, "I only want to see 'git log' output with 'master'
decorated" (i.e. not specifying "this class of refs I can glob by
using the naming convention I am using" and instead enumerating the
ones you care about) does not sound like a sensible thing people
often want to do, so making it follow the other codepath so that
people can say "refs/tags" to get "refs/tags/*", while still allowing
such a rare but specific and exact one possible, may not sound too
bad to me.
