It's hard to cater for all tastes and needs. In this case, it's a simple change
in llex.c (at least for parse errors in files):
In Lua 4.0, change luaX_syntaxerror in llex.c to
void luaX_syntaxerror (LexState *ls, const char *s, const char *token) {
char buff[MAXSRC],*b;
luaO_chunkid(buff, ls->source->str, sizeof(buff));
if (buff[0]=='f') {
b=buff+6;
buff[strlen(buff)-1]=0;
}
else
b=buff;
luaO_verror(ls->L, "\n%.80s:%d: %.99s; last token read: `%.30s'",
b, ls->linenumber, s, token);
}
This will affect both lua and luac.
