git-shortlog man page missing a bunch of options

[Pratyush Yadav <me@yadavpratyush.com>]

Hi,

I was looking at the git-shortlog man page today and realized that it 
didn't mention an option that I have used before '--no-merges'. Looking 
further, there are a lot of options that are not documented.

One fix would be to include rev-list-options.txt (which is where I 
assume these options come from), just like git-log does.

But rev-list-options.txt is a rather large file and I'm not sure if 
including it in both git-log and git-shortlog would be a good idea. The 
way I see it, git-log is the "primary" log interface, and git-shortlog 
is a "secondary" log interface, so git-log warrants such a large man 
page, but git-shortlog doesn't especially since most options are 
repeated. So maybe it is a better idea to just include a pointer to 
git-rev-list in the shortlog man page.

I'll send in a patch after some suggestions on which alternative to go 
for.
