I think the problem, at heart, stems from bash trying do the right thing
for Emacs. This is not made any easier by the fact that Emacs needs
different things, depending on whether we are in shell or ansi-term.
Really, Emacs should just explicitly request which features it needs,
rather than saying "I am Emacs, now be right".

And there is a simple workaround should we wish for consistent EMACS
behaviour in shell and term, which can be applied with in .bashrc or
having Emacs inject a command into the new shell.

It's "Phillip" actually --- the misspelling is one of the reasons I
normally go by "Phil".
