[PATCH] gitweb: Re-enable rev-list --parents for parse_commit.

[Robert Fitzsimons <robfitz@273k.net>]

Re-enable rev-list --parents for parse_commit which was removed in
(208b2dff95bb48682c351099023a1cbb0e1edf26).  rev-list --parents is not
just used to return the parent headers in the commit object, it
includes any grafts which are vaild for the commit.

> Actually --header output gives us original parents. Rewritten parents
> (available with --parents) include also grafts and shallow clone grafts.
> For parse_commit we want --parents, for parse_commits we don't want it
> because --parents affects --full-history.

Heres a patch the re-enables --parents for parse_commit.
