That was exactly my initial reaction.  Or "recurse-submodules" gets
renamed away, and "recommend" gets added---now "--rec" is still not
ambiguous as "recursive" is marked not to participate in the
disambiguation (I think OPT_NOCOMPLETE should at least be renamed to
OPT_NO_DISAMBIGUATION or something---if we were to use it for the
purpose of marking an option as "not participating in
disambiguation", but I am fairly negative on the approach).

And my initial reaction was followed by "don't we want a more
explicit link only between recursive and recurse-submodules?",
which exactly matches what you said below ;-)

The "bit more work" is something that is worth doing in this case, I
think.

Thanks.
