[PATCH] gitk: do not limit tree mode listing in the file list panel to current sub-directory

[Alex Riesen <alexander.riesen@cetitec.com>]

From: Alex Riesen <raa.lkml@gmail.com>

The previous behavior conflicts with the "Patch" mode of the panel,
which always shows the changes from the top-level of the repository.
It is also impossible to get back to the full listing without restarting
gitk.

Well, I just tried your suggestion. 'ls-files' doesn't have --full-tree, so
for those it is just cd-up.

It is on top of the re-sent series.
