Updated version of Alexandre Oliva’s patch to make forward accent
sorting the default.

The only locale which currently needs backward accents sorting is fr_CA.
Therefore, forward accents sorting should be the default.

Before this patch, backwards accent sorting was the default and all
locales except fr_CA had to use

    define DIACRIT_FORWARD

before

    copy "iso14651_t1"

Most locales didn’t do that and thus got the inappropriate backwards accents sorting
by accident. Now only the fr_CA locale needs to use

    define DIACRIT_BACKWARD

before

    copy "iso14651_t1"
