[PATCH] gitk: Allow unbalanced quotes/braces in commit headers

[Kevin Ballard <kevin@sb.org>]

When parsing commits, gitk treats the headers of the commit as tcl lists.
This causes errors if the header contains an unbalanced quote or open brace.
Splitting the line on spaces allows us to treat it as a set of words instead
of as a tcl list, which prevents errors.
