This pattern must exclude questionables on either NTFS or HFS+; it
is ironic that it is not even sufficient to limit ourselves to the
Portable Character Set [*1*], but such is life.

By the way, doesn't ls-files take pathspec glob, saving one extra
process to run grep?

I specifically did not do that, sorry for omitting the rationale from the
commit message. The reason why I have that grep is so that the backslash
can also catch non-ASCII characters, such as "Hellö-Jüniö".

And there is another very good reason to keep the grep: the problem I just
reported is *caused* by your avoiding the grep call.

In my tests, at least, `git ls-files '*\*' lists *all* files in
subdirectories. In other words, it matches the *forward* slash. This also
happens when I run the command in cmd.exe instead of Git Bash, meaning
that it is *not* caused by some MSYS2 path conversion from pseudo-Unix to
Windows paths. That only leaves the conclusion that some of our pathspec
code tries to be helpful and takes a backslash for a directory separator.

In light of these problems, and also in light of the fact that the
test-lint-filenames code is hardly performance critical, I am strongly in
favor of reverting to using grep.
