Ah...so what we want then is for all of these cases to work:

\d foo \d bar
\d foo; \d bar
\d foo; \d bar;
\d foo; \d bar

Makes sense...I never combine backslash commands on the same line,
but it is possible. In that case, how about just moving this section:

  if (semicolon) {
    int i;
    for (i = strlen(options_string)-1; i && options_string[i]==';'; i--);
     if (i<strlen(options_string)-1) options_string[i+1]='\0';
  }

to right after here, where we find a "normal word"?

  strncpy(return_val, &options_string[pos], token_end);
  return_val[token_end] = 0;

(and changing options_string to return_val)

that should allow us to catch all the cases above, if I am
understanding the objection above correctly.
