[PATCH] remote-hg: fix handling of file perms when pushing

[Max Horn <max@quendi.de>]

Previously, when changing and committing an executable file, the file
would loose its executable bit on the hg side. Likewise, symlinks ended
up as "normal" files". This was not immediately apparent on the git side
unless one did a fresh clone.
