No, I do not. I was just wondering if a non-submodule user
may see differences between different commands now.

For example "checkout -b" already quotes 'external data', which
would be inline with this proposal, but there may be others.
My question was rather an encouragement to check the code base
if there are other occurrences left that do not quote.

In an ideal code base we could just grep for any %s that has no
surrounding quotes, but of course it is not as easy in the real world:
* some outputs use %s construction for non-human consumption
  in e.g. the diff machinery
* sometimes we play sentence lego, stringing words together
  which also is using %s unquoted correctly.

Yes. I like the direction this patch is going.

A note on 'external data':
For branchs, paths, submodule names a single quote seems
to be best (my opinion), whereas in e.g. git-status:

    Submodule 'sm1' 0000000...1beffeb (new submodule)

parens seem to do a better job as they describe the state,
not reproducing external data. (This is also the place
where I was reminded of potential sentence lego)
