Subject: [PATCH v2 7/8] real_path(): properly handle nonexistent top-level paths
Date: Fri,  7 Sep 2012 00:41:03 +0200	[thread overview]
Message-ID: <1346971264-23744-8-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1346971264-23744-1-git-send-email-mhagger@alum.mit.edu>

The change has two points:

1. Do not strip off a leading slash, because that erroneously turns an
   absolute path into a relative path.

2. Do not remove slashes from groups of multiple slashes; instead let
   chdir() handle them.  It could be, for example, that it wants to
   leave leading double-slashes alone.
