Lua 5.2.0-alpha already does that. As far I as can see, the patch
simply replaces the original code
if (badoption[1] == 'e' || badoption[1] == 'l') {
luai_writestringerror("%s: ", progname);
luai_writestringerror("'%s' needs argument\n", badoption);
} else {
luai_writestringerror("%s: ", progname);
luai_writestringerror("unrecognized option '%s'\n", badoption);
}
with
luai_writestringerror("%s: ", progname);
if (badoption[1] == 'e' || badoption[1] == 'l')
luai_writestringerror("'%s' needs argument\n", badoption);
else
luai_writestringerror("unrecognized option '%s'\n", badoption);
thus saving one or two lines.
Thanks for the patch anyway.
