IMO Simon's suggestion of something like :normalizetype or :normalize
or :normtype would be even better -- you could abbreviate it as just
:n .  It is also more accurate; the correct term for what the command
should do is in fact "normalize", and it may not in fact end up making
the type any simpler.
