I'm sorry. I wasn't as clear as I should have been.
the two-char ^[ was used in the e-mail message, where-as the single-char
^[ (ie. Ctrl-[) is used in the PS1/PS2 strings. You use of \e has the same
effect as a ^[.

This works for me, though I do have /etc/inputrc with:
# Use a single line for display
set horizontal-scroll-mode on
This causes the prompt to scroll off the left edge as I type long commands.
