Sounds good to me.  It's less code, and the code it calls
(cygdrive_posix_path) is more efficient because it doesn't have to loop
through all mounts.  As long as you're ok with the change in behavior
that:

mount C: /c
mount

will now show C: on both /c and /cygdrive/c, instead of just /c as before
(this is the behavior all of that de-duplication mess was trying to
replicate).
