[PATCH 3/3] gitweb: Add author initials in 'blame' view, a la "git gui blame"

[Jakub Narebski <jnareb@gmail.com>]

For example for "Junio C Hamano" initials would be "JH".  Of course
initials are added (below shortened SHA-1 of blamed commit) only if
group of lines has 2 lines or more in it.

Let the bikeshedding begin!

Should it be "JH" or perhaps "J.H." for "Junio C Hamano"?  Or perhaps
username part of author email would be better solution than initials?
Should we use different style for those initials?

This patch was inspired by me adding the same feature in similar 
'blame_incremental' view in
