[PATCH gitk 4/4] gitk: recognize -L option

From: Thomas Rast <trast@inf.ethz.ch>

Message-ID: <a9d0af8f1266cad6edcabd4d8a54ef5d2bb87ab4.1370806329.git.trast@inf.ethz.ch>
In-Reply-To: <cover.1370806329.git.trast@inf.ethz.ch>

This gives line-log support to gitk, by exploiting the new support for processing and showing "inline" diffs straight from the git-log output.

Note that we 'set allknown 0', which is a bit counterintuitive since this is a "known" option. But that flag prevents gitk from thinking it can optimize the view by running rev-list to see the topology; in the -L case that doesn't work.
