[Murray Cumming <murrayc src gnome org>]

commit 31d34b516699d7e8e6b847bd684afcc035ab95f4
Author: Murray Cumming <murrayc murrayc com>

    Gio::Action: print_detailed_name() Make this templated.
    
    Renaming the original method to print_detaild_name_variant().
    This method is new in this development cycle, so we may still
    change it.
