The POSIX specification requires that the prompt be issued to stderr:-
1468 PS1 Each time an interactive shell is ready to read a command, the value
of this
1469 variable shall be subjected to parameter expansion and written to
standard
1470 error. The default value shall be "$ ". For users who have specific
additional
1471 implementation-defined privileges, the default may be another,
1472 implementation-defined value. The shell shall replace each instance
of the
1473 character '!' in PS1 with the history file number of the next command
to be
1474 typed. Escaping the '!' with another '!' (that is, "!!") shall place
the literal
1475 character '!' in the prompt. This volume of IEEE Std 1003.1-2001
specifies
1476 the effects of the variable only for systems supporting the User
Portability
1477 Utilities option.
I'm guessing that that is why your patch was rejected.
