This is operating on a string(TOLOWER)-converted path already.
On case-sensitive filesystems it does not make sense to call
REALPATH for these.  The code is doing string manipulation of
the paths at this point.

Please explain the case you're hitting in more detail.  How
does one end up with a non-canonical path in the first place?

Thanks,
