I'm not sure that I'd want to. Handling case insensitivity is fine
when you're restricting everything to ASCII, but it's rather harder
when you allow all of Unicode. For instance, U+0069 and U+0049 would
be considered case-insensitively equal in English, but in Turkish,
they're different letters; U+0069 upper-cases to U+0130, and U+0049
lower-cases to U+0131. Much safer, when you're writing generic tools,
to simply require case sensitivity. And you can't easily know whether
the file system is case-sensitive, case-retaining, or case-folding;
you could easily have multiple mounts that differ, so
"/home/rosuav/foo/bar/quux" might be the same as
"/home/rosuav/FOO/bar/quux", but the other four components are all
case sensitive. Yes, it really is possible.
