Use repo_name as literal in bug_project

Additionally, fix E501 line too long violations in configuration file.
This should help smoothen inclusion in projects where such checks are
applied.

Note that the giturl line uses the noqa tag instead of the multi-line
approach. I find that it reads better that way.
