[PATCH] cogito: allow filenames with spaces in cg-commit

[Jan Veldeman <jan.veldeman@advalvas.be>]

Fixes the filename handling in cg-commit.

To allow spaces in the filenames, the filenames are kept in an array.
(The trick with zero bytes is harder to do when storing the filenames in
a variable).
"${commitfiles[@]}" is used where the filenames are needed as separate
arguments, this expands into "file 1" "file 2" ...
"${commitfiles[*]}" is used when a check is made for the existence of the
parameter, this expands into "file1 file 2 ..."

The eval changedfiles=($(... | sed ...)) is used to place the result of
git-diff-cache into the array. (I couldn't find a cleaner solution to do
this)
