To have trouble I think you'd need to have two files in a project
whose name only differed by slashes: e.g. "a\b.c" and directory "a"
and "a/b.c". Mistakenly thinking a path is relative might cause some
problems but I can't think of how they would manifest.
I'm happy to add the band-aid; do you have an idea of what to call it?
set strict-filenames?

The POSIX parts will work in UTF-8, since no multi-byte UTF-8
characters contain printable 7-bit ASCII. Other encodings, or with
the tolower check, I don't know.
