So here's the thing about this patch: I despise Mercurial's gitweb style
almost as much as I despise git itself. It is both hideous and arcane
like its namesake and makes me cringe whenever I see it on a public
website with name 'Mercurial' attached to it. If I could delete it, I
would.

So I'm really reluctant to add new features to it that aren't also
present in the default style in some fashion, as that will encourage
even more people to use it.

So I think we should figure out whether it makes sense for this to be a
stock feature of hgweb styles.

Upsides:

- useful at-a-glance summary of relative amount of changes

Downsides:

- not well-defined for merges
- file lists can be arbitrarily long
- diffstat is monospaced ASCII - not really a great match for the web
- performance impact for large diffs

Possibilities:

- add a fold-out to paper to show the diffstat
