[PATCH]  file seperator handling for the other 'OS'

From: K Thananchayan <[e-mail]>

The following patch maintains repo root relative source file names in
canonical form (with '/' as file seperator).

Mercurial calls os.path.join, os.path.normpath, os.path.walk that use
platform's file seperator. This patch does not change seperator in
these circumstances (except when the result refer to source files).
