[PATCHv6 1/8] gitweb: refactor author name insertion

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Collect all author display code in appropriate functions, making it
easiser to extend them on the CGI side, and rely on CSS rather than
hard-coded HTML formatting for easier customization.
