The new switch differs by one dash, so I'd think the double dashed
version would still autocomplete.

Unrelated to this, but more to submodules:
There is submodule.recurse which you may want to set.
Would you be interested in a more specific config option there?
(i.e. grep.recurseSubmodules to only apply to grep recursing into
submodules, just like fetch.recurseSubmodules only applies to fetch)

That sort of makes for the grep case, but not for other commands.
