// marked with W_("foo) in the source code. xgettext can then add a comment
// to all such strings to inform translators. The following option needs to
// be added to XGETTEXT_OPTIONS in po/Makevars or in an equivalent place:
//
// '--keyword=W_:1,"This is word wrapped at spaces. The Unicode character U+00A0 works as a non-breaking space. Tab (\t) is interpret as a zero-width space (the tab itself is not displayed); U+200B is NOT supported. Manual word wrapping with \n is supported but requires care."'
//
// NOTE: The double-quotes in the --keyword argument above must be passed to
// xgettext as is, thus one needs the single-quotes in Makevars.
