8137d2b4 - xgettext: Fix double-free in singular/plural argument extraction

xgettext: Fix double-free in singular/plural argument extraction After commit 6aa7b7ed in 2009, xgettext assumed that ARGNUM1 and ARGNUM2 of -k are different. That could cause an double-free in exceptional cases. Reported by Johan Liljegren in: <https://lists.gnu.org/archive/html/bug-gettext/2014-10/msg00028.html>. * xgettext.c (arglist_parser_remember_literal): Don't assume that ARGNUM1 and ARGNUM2 are different.
