Re: [PATCH 1/4] Implement normalize_absolute_path

[David Reiss <dreiss@facebook.com>]

This is close enough to what I want that I could definitely use it if it
were in the main tree.  I read through most of that thread, but I
couldn't figure out what ever happened to your patch.  (I couldn't find
a clear rejection, but I also don't see it in master.)
