    Try to fix C_ macro after switch to intltool
    
    mcatanzaro:  Hey i18n folks, I just switched Epiphany from intltool to
    directly using upstream gettext. It mostly works fine but I lost
    translations for some strings in ephy-web-view.c that were using the C_
    macro to add contexts. I do have USE_MSGCTXT = yes in my Makevars file.
    Any clues what might be wrong?
    ueno:  mcatanzaro, is --keyword=C_:1c,2 in XGETTEXT_OPTIONS?
    mcatanzaro:  ueno: Nope, thanks!
