[PATCH 04/11] i18n: add--interactive: mark plural strings

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

 



Mark plural strings for translation.  Unfold each action case in one
entire sentence.

Pass new keyword for xgettext to extract.

Update test to include new subrotine Q__() for plural strings handling.
