True, but these non-canonical filenames can also arise if you do "mount -f
-o managed EXISTING-WIN-DIR". The "just don't do that" argument also
applies there, of course, but that's an idiom used by many pre-cygport
package build scripts. (Cygport leaves off the -f, avoiding the problem.)
And, of course, any non-Cygwin program writing to the managed directory can
create file names not in the canonical form.
