PATCH: environ style

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

The environ style in _sudo is being looked up without the conventional
:completion: prefix. So unfortunately this fix is going to break the
style for anyone that uses it. Is anyone especially upset by that?
I'd also be tempted to put the command in the context if the command is
already on the command-line much as we do for git/svn etc subcommands.
