bug in man page of lex(1)

[David Lai]

The lex(1) man page says:

	...yyless(p) ... p should be between yytext and yytext+yyleng

however the lex users manual says:

	yyless(n), n=number of chars to retain in yytext

The bahaviour of lex is that of the latter.  So change the lex(1)
man page to show that the argument to yyless() is a number, not a
pointer.

(Error appears in Sun (bsd) manuals, and HPUX (SysV) manuals).
