[PATCH] gitk: Decode the "-n" argument properly for Edit View

[Jim Ramsay <i.am@jimramsay.com>]

Running 'gitk -n 42' and selecting View > Edit View... would previously put the
'-n' half of the argument-pair in the box labeled "Additional arguments to git
log" and the '42' in "Branches & Tags".  Parse this pair properly and use the
numerical portion for the 'limit' value.
