  vc-git.el: Switch to using git-blame instead of git-annotate.
  git.el: Fixed inverted "renamed from/to" message.

+Setting the environment variable GITWEB_CONFIG will tell gitweb to use
+the named file (i.e. in this example /etc/gitweb.conf) as a
+configuration for gitweb.  Perl variables defined in here will
+override the defaults given at the head of the gitweb.perl (or
+gitweb.cgi).  Look at the comments in that file for information on
+which variables and what they mean.
