[PATCH 0/3] gitweb: 'blame' view improvements

This patch series was inspired by the study before sending proposal
for git-blame improvements; I have noticed that "previous"/"parent"
blame header was already implemented, just not documented:
  Subject: git-blame: Documenting "previous" header
  Message-ID: <200907071423.40938.jnareb@gmail.com>
  http://thread.gmane.org/gmane.comp.version-control.git/122837

Therefore proposal got cut down to tree blame:
  Subject: [RFC] Tree blame (git blame <directory>)
  Message-ID: <200907071058.39390.jnareb@gmail.com>
  http://thread.gmane.org/gmane.comp.version-control.git/122830

Using "previous" header should improve gitweb performance and (as I have noticed during implementing it) allow to follow 'linenr' links correctly through rename in a blamed commit.

Marking "boundary" somewhat was required to make it possible to distinguish which 'linenr' links would lead to parent of a blame commit (to previous version of a file), and which would elad to blamed commit. Current styling is up to debate.

After implementing using "previous" header in 'blame' view (which would allow to do the same for proposed 'blame_incremental' view) I remembered that last version of implementing 'blame_incremental' added author initials a'la "git gui blame". So I did the same for non-incremental 'blame' view. Exact formatting is up to debate.
