But it means the problem will not be solved in the general case before a while.
It must also have been problematic for some time, so I guess we are not in a hurry either.

I agree there should be Dir.escape or Dir.escape_glob.

Can you give examples? If it works for every case except FNM_NOESCAPE, I think it is better to have a single simple way.

This is inspired by https://github.com/rails/rails/issues/6010.

Basically, if you do a Dir.glob in a directory whose name contains a glob character, things break. It would be nice to have a method which would escape the input so that we can Dir.glob inside of those directories.
