Message-ID: <1272985539-24586-1-git-send-email-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.
