Right. My point is that I am not sure anybody ever really _wants_ to do
this, versus:

  git cmd -- "$pattern1" "$pattern2"

Because patterns tend to be small in number and made with predictable
characters known to the script writer. It is sets of arbitrary filenames
that tend to be long and contain random junk.

I had just assumed we would forbid, but yeah, you could have a switch to
handle either case. That is much nicer to the corner case people.

It is not about "forcing to type". It is about "did not realize this was
a potential pitfall and did not write it in the script in the first
place".
