-The gnulib implementation return a password of arbitrary length read
-from /dev/tty (or stdin), other implementations may truncate the
-password to PASS_MAX or 8 characters.
+The returned password is truncated to PASS_MAX characters on some platforms:
+MacOS X 10.5 (128), FreeBSD 6.2 (128), NetBSD 3.0 (128), OpenBSD 4.0 (128), AIX 5.1 (32), HP-UX 11 (8), IRIX 6.5 (32), OSF/1 5.1 (80), Solaris 11 2010-11 (8, even less than PASS_MAX), Cygwin (128).
+The gnulib implementation returns the password untruncated.
