Yes, you are right.  The problem is that I have PROMPT_COMMAND set to a
function that exports PS1.  I had fixed the problem but not propagated
the solution to all other machines.  The correct prompt looks like this:

  \[\e[35m\][\t] \[\e[32m\]\u@\h \[\e[36m\](\!) \[\e[33m\]\w\[\e[34m\]\[\033[0m\]\n$

The extraneous symbols were coming from the following fragment

  \[\033]2;\u@\h\a\]

which seems to be some sort of attempt to use the text attribute "dim"
(2;), which is ignored or not displayed for most of my terminals, but
produces

  ^[]2;loris@pi^G

when the shell is run with Emacs.

Sorry for the noise.

Cheers,

Loris
