Unless someone accidentally makes a filename with a $ in it, or in
bash one one with a ! in it, or in windows one with two %s in it.

Except that in linux, the rm command sees the - and gives an argument
parsing error.

That's by no means the fault of the filesystem library, but it's be
great if it were handled gracefully, since we have a type system and
know that the coder isn't trying to specify flags.

(I suppose theoretically there could be a problem in windows too, with
a linux-thinking script running something like "del /test.txt" and
getting "Invalid switch - "test.txt".")
