git_config: add support for remote '.'

As a fix for issue #149, this patch add support for the remote '.'

As an alias for the local repository, remote '.' is lacking a fetch =
config in .git/config.

Without such refspec, repo info --overview is not able to process a
local tracking branch.

v2: Check for name == '.' before checking if merge starts with refs/,
    since the case where it's not is invalid.
