Note that cmdutil isn't a standard library. IMO the boilerplate when using
argsparse from the core library is negligible. But I wouldn't insist for a tool
like that.

[Wladimir Palant, 2016/03/10 12:36:36]

No, it isn't a standard library but it is documented Mercurial API and
recommended for Mercurial extensions. I think that by reimplementing we would
create a larger risk of incompatibilities than by sticking with it.

[Sebastian Noack, 2016/03/10 12:44:28]

I just realized that this is a Mercurial extension, and that this module comes
from Mercurial's API. So it actually makes sense to use it here.

Nit: Why not modifying args inline as above using args.extend()?

[Wladimir Palant, 2016/03/10 12:36:36]

Done.
