Obviously, what you call "the exact (garbage) codes specified in your 
PS1" in RXVT, MRXVT, URXVT, (KDE)Konsole produces:

address@hidden ~/downloads/cygwinports
$

in which 'address@hidden' is in green, '~/downloads/cygwinports' in yellow 
and '$' white.

It is only in Emacs shell mode (M-x shell) it produces 'garbage', both 
in GNU/Linux and Cygwin builds of current trunk.

Is there a method to redefine PS1 in .emacs?

Using

'address@hidden \w\n $'

for PS1 would be enough.
