dpkg will prompt if both:
a) you have changed a config file
b) a new version of the config gile is available

otherwise it does nothing or promtps.

PROMPT_COMMAND is not the same as the title string specified with -T.
PROMPT_COMMAND is what your prompt displays, e.g.
leroy@debian:~$

bash.bashrc is sourced _before_ your ~/.bashrc, so any settings in it
are overridable by your ~/.bashrc.  Are you sure you changed this file,
or are you assuming it must be this since -T isn't doing what you
expected?  I would start by looking elsewhere, although if this file did
get ovrwritten and your changes lost, that would be a serious bug.
