gitk - show newly created files

When specifying a filename as an argument to gitk, ie.

$ gitk apply.c

gitk does not show the diff when the file newly created.

That 'newly created' commit is the last one gitk gets from 'git-rev-list' so gitk thinks it has no parent while it normally does (except that the commit itself is the root commit).

This patch is to (try to) fix this problem.

P.S, is it good if gitk also has a '--root' option like git-whatchanged?
