[PATCH] gitweb: gitweb_check_feature always return list

[Jakub Narebski <jnareb@gmail.com>]

Modified feature_blame so it returns one-element list and not scalar,
thus making gitweb_check_feature always return list.  Updated comment
to explain that part.

This is continuation of Aneesh Kumar work:
  gitweb: Fix git_blame
"Converting the default values to array broke the git blame enable
 disable support. Fix the same."

We could modify %feature hash so the 'default' value could be either
array reference or a scalar instead.
