Re: [PATCH] submodule: deprecate --recurse-submodules=""

Taylor Blau [off-list ref] writes:

So here we'd be doing the equivalent of

    *v = RECURSE_SUBMODULES_OFF;

when trying to parse `--recurse-submodules=""`. Should this advice
instead say "[...] Use --no-recurse-submodules without an argument,
which does the same thing"?

Sounds right.  So there is nothing to change here, I guess.

If --recurse-submodules="" does something people do not expect to
happen, an warning might be warranted, but I somehow do not think
that is the case here.  If we are not hurting anybody by accepting
that (possibly unusual) form, I do not think we would want to add an
extra warning, either.

Thanks.
