Not sure. Peter stated the French locale was wrong for the Debian they
were using, and he should know, so I am going to wait for more feeback.

One thing that has me confused is that psql/print.c doesn't check for a
zero-length string for thousands_sep in setDecimalLocale, so I am not
thinking that is wrong and should skip "" like we do in formatting.c.
