Umm, I see I was a little TOO terse.  The characters you're seeing are the
way emacs renders the ESC (^[) character from the ANSI escape sequences
that are part of your prompt ($PS1).  Their purpose is to set the colors
on terminals that support it.  Emacs's terminal emulation doesn't support
those escape sequences, and thus tries to render them literally.
Arguably, emacs should support at least the color sequences, but SHTDI.

PS1 is usually set in .bashrc or .bash_profile, or /etc/profile (or
inherited from the environment).  It may be simplest to just add a line at
the end of your .bashrc saying "if [ $TERM = emacs ]; PS1='$ '; fi".
HTH,
	Igor
