backport SVN commit 1087403 by coles:

Proof-reading changes. Note that the plural form call is still needed even if '1 bit' wouldn't be sensible - there are languages that have different plural forms depending on if the number ends with, say, a three, or a four etc.

MERGE: none (already in trunk)
