[Bug] yytext() return longer than expected with lookahead [sf#72]

**Reported by *anonymous on 2005-03-16 22:24 UTC**
If following by design

pattern:
ab / cde { System.out.println(yytext()); return 2; }
abcd / f { System.out.println(yytext()); return 7; }

string:
abcde

result
prints out "abcd" while returns 2.
