The change from "submodule" to "./submodule" was not explained in
the proposed log message.  I think this is necessary for "git
submodule add" to function as expected, but if that is why we are
making this change, perhaps we should mention it?

What does "patterns" refer here (another one in the next hunk)?

Is this supposed to have become "git submodule add ./xyzzy"?  Or
"git add xyzzy" will trigger "don't add gitlink" warning but you can
write "git add ./xyzzy" as a way to work around the warning?

Or is this an incomplete change that wasn't spotted during
proofreading?

Why does this one (and only this one) look different?  Everybody
else changed "git add A" to "git submodule add ./A", it seems?

I think I saw a code section that was touched in the previous patch
that hand-crafted .gitmodules file to make the gitlink it adds into
a submodule.  It is unexpected and puzzling that there is no removal
of that "cat >.gitmodules" from t4060.
