Teach 'git merge' the --continue option which allows 'continuing' a
merge by completing it. The traditional way of completing a merge after
resolving conflicts is to use 'git commit'. Now with commands like 'git
rebase' and 'git cherry-pick' having a '--continue' option adding such
an option to 'git merge' presents a consistent UI.

So here is a quick patch that adds the --continue option. I need to add
some tests (suggestions for where to start are welcome).
