Revert (kind of) the change in 1.12 of the ancient mksyntax.sh script 

(undoing the effect of that commit on syntax.h when it was
being dynamically generated) from 1996.   This means that the shell
parser is now locale independent, so scripts that work anywhere will
work consistently everywhere.   Inspired by a similar change in
FreeBSD's sh (from 2010) - the original change in the other direction
came from FreeBSD as well....   Note that this does not in any way
add any kind of support for locales to sh (which is a whole different
problem.) (from kre)
