From 28e853e6b085c625af03be5211ded3f307c0fd96 Mon Sep 17 00:00:00 2001

Subject: Add a 'categories' parameter to 'select_words_except'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This way the -c/--category flag can also work together with the
-i/--inflection one.
