The only problem with that is that it confuses bash's command-line
editing, which thinks that all that stuff in your prompt takes up
screen space and therefore gives you less than the whole line to work
with. Better, IMO, to use PROMPT_COMMAND - but then you don't have
the PS1 escapes like '\h', so it takes a little more work to get that
info. This is what I use to keep track of current hostname and working
directory:
PROMPT_COMMAND='echo -ne "\e]0;$(hostname):${PWD/$HOME/~}\a" '

If you use bash, pass the -e option to echo to have it honor escape
sequences, and you can use \e for "escape" (ESC = decimal 27 = octal
33) and \a for "alert" (BEL = 7).
