git/gitweb - feature request: Add description to the branches.

Hi:

        First, thank you for this great tool.

        One thing I'm missing is a way to describe a branch. It can be
        done in the $GIT_DIR/description, the first line for the whole
        repository and the rest for the branches. So description file
        for the git.git repository could be:

[description] The core git plumbing pu: Proposed updates rc: Release candidate todo: Todo list [/description]

        And it can be added to the gitweb tool.

        Thanks.

        Santi
