Log Message:
add a hack to properly handle '--' as first argument -
it's ignored if it would cause syntax error, otherwise treated as common
string; this is so that both 'expr -- : .' and 'expr -- foo : .' works
This addresses standards/11230 by Ben Harris.

while here, make all global variables but main() static, use const more
