Thanks.

While I like the idea, there are a couple of minor problems with the
patch.  First, the Documentation directory is in Junio's tree, not
mine, so the change to gitk and the change to Documentation need to be
separated.  Secondly, please use 4-space indentation rather than
8-space for consistency with the rest of the file.  See also the
comments below.

No need to say [expr {$i}] here; [lindex $argv $i] works just fine.

Also, if i is now >= [llength $argv], we'll get an empty string in
cwd_path.  Is that what you meant?  Shouldn't we display an
appropriate error message instead of trying to cd to ""?
