/bin/echo, echo alone, and "builtin echo" all produce identical
(wrong) results on RH9:
[cricket : phutchis]$ echo "${MY_TITLES}\c"
\0033]2;cricket\0007\0033]1;cricket\0007\c
[cricket : phutchis]$ /bin/echo "${MY_TITLES}\c"
\0033]2;cricket\0007\0033]1;cricket\0007\c
[cricket : phutchis]$ builtin echo "${MY_TITLES}\c"
\0033]2;cricket\0007\0033]1;cricket\0007\c
"echo -e" works on RH9, but not on any of the other systems I use.

To me, fixing the breakage in a new release seems more viable than
constructing an exponentially-exploding maze of workarounds. I was
hoping for something like a "set" command that would cause the new
bash (or echo) to behave like the old one.

I suppose I could do something like
if [system is RH9]; then
ECHO_CMD="echo -e"
else
ECHO_CMD=/bin/echo
fi
...
$ECHO_CMD "${MY_TITLES}\c"
but what do I put inside the [], that will run on all systems,
to reliably identify "Red Hat 9"? Apparently $BASH_VERSION is
irrelevant, and $OSTYPE on RH9 just says "linux-gnu".
