(Such constructs assuming a plural bring translation problems.
First, some languages use more than two plural forms - Russian, Bosniac, Irish, etc.
Second, "No" in English is translated to "Aucun" in French, and "No" is followed by plural and "Aucun" by singular!
Better use support for "plural forms" as offered by gettext utilities.)
