Thanks, Juri.  It works fine.  I'll use it.

I was going to propose another (more flexible) alternative: Instead of
storing a boolean value in a variable (to switch echoing on/off),
store a time delay, after which the echoed text would be removed (if
was not already removed by another event).  A value of 0 would mean
"don't echo", and a value greater that some limit would mean "never
remove" (as now).

But if no one else thinks that this change is worthwhile, you can
close this bug report.

Thanks again.
