I suppose it is.  I'm still getting the "are the same file" failure
(which, BTW, only occurs with check_case:relaxed or check_case:adjust --
with check_case:strict the error is "Filename exists with different
case").

Note that Dave Korn was running all commands from the cmd shell (though he
claimed that "mv" worked for him from bash as well).

This is in no way Cygwin-related.  The above uses the standard Bash
pattern removal expansion (see the "Parameter Expansion" section in the
bash manpage), as well as the current process id ($$).

For those too lazy to look this up, the script renames the first file to
something unique, and then renames that to the second name.  The pattern
removal is needed to allow trailing slashes (e.g. "mvv a/ b/").
