So how do you propose splitting the patches to accomplish this? One 
patch to add mailmap support and another patch to modify how angle 
brackets are handled in the email addresses? Which patch goes first and 
who will fix the angle brackets? Are you volunteering? ;)

I haven't done much C programming in years and wasn't familiar with 
neither the git nor cgit code, so it took me a little while to figure 
out how to add mailmap support to cgit. I did it because we recently 
added mailmap files to our local git repos to clean things up and I 
noticed that cgit wasn't using them. I just looked at the filter code a 
little and it looks a bit complicated to my novice eyes. I'm not sure 
how to patch it to just modify only email addresses passed into it. 
Another option might be to just just use another char string to wrap the 
email address in angle brackets before opening the filter in the caller 
and pass that instead?
