[Murray Cumming <murrayc src gnome org>]

commit f73bd15a818531e81dac4f81f3ac8e659f9c84bf
Author: Murray Cumming <murrayc murrayc com>

    Avoid a indirect gtksourceviewmm include
    
    Because it currently causes so many warnings about #warning (in the
    gtksourceview headers) being a GNU-only extension.
