Subject: path/filepath: fix Abs on Windows
X-Git-Tag: go1.8beta1~465
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=8f91865e1b2f2df95fb4833babbd0a8fb26085c8;p=gostls13.git

path/filepath: fix Abs on Windows

The filepath.Abs function in windows did not call Clean as the
documentation claimed.  This change not only fixes that behavior but
also adjusts TestAbs to verify Abs calls Clean as documented.

Fixes #17210
