git log: add '--merges' flag to match '--no-merges'
I do various statistics on git, and one of the things I look at is merges, because they are often interesting events to count ("how many merges vs how much 'real development'" kind of statistics). And you can do it with some fairly straightforward scripting, ie git rev-list --parents HEAD | grep ' .* ' | git diff-tree --always -s --pretty=oneline --stdin | less -S will do it. But I finally got irritated with the fact that we can skip merges with '--no-merges', but we can't do the trivial reverse operation. So this just adds a '--merges' flag that _only_ shows merges. Now you can do the above with just a git log --merges --pretty=oneline which is a lot simpler. It also means that we automatically get a lot of statistics for free, eg git shortlog -ns --merges does exactly what you'd want it to do.
