Yes.  Edit /Cygwin.bat and add "unset HOME" right before invoking bash.

bash uses a different set of escape codes.  The below is actually a bug in
the default /etc/profile -- the '^[' symbols should be literal Esc (0x1B)
characters, and '^G' should be 0x07 characters.  I've reported this
before, but it probably is time to bring it up again.

Those aren't escape codes, those are improperly pasted control characters.
