[RESEND] [PATCH] Fix tree mode of the file list for files containing curly brackets

[Alex Riesen <raa.lkml@gmail.com>]

As far as I could understand the online documentation the [lindex ...]
thing expects an array, which a string produced by git-ls-tree is not.
So [split ...] it first, to get a real Tcl string-array.

For instance:

    $ git init
    $ date >file
    $ git add . && git commit -m1
    $ git mv file '{a-b}.a.b'
    $ git commit -m2
    $ git mv file '{a-b}.a.b{'
    $ git commit -m3
    $ git mv file '{a-b}.a .b{'
    $ git commit -m4
    $ gitk

Now switch the file list from "Patch" to "Tree":

    list element in braces followed by ".a.b" instead of space
    list element in braces followed by ".a.b" instead of space
	while executing
    "lindex $line 1"
	(procedure "gettreeline" line 9)
	invoked from within
    "gettreeline file11 4b155a05282eeccd7c8fd381b22ed442efde2850"
	("eval" body line 1)
	invoked from within
    "eval $script"
	(procedure "dorunq" line 9)
	invoked from within
    "dorunq"
	("after" script)

And, as I actually do know nothing about Tcl, it does not work for
files with spaces. The last lindex is obviuosly wrong, it breaks names
with whitespaces.

I rebased the patch on current master.
