I'm really surprised by the amount of interest to this topic and by the
amount of time spent on it.  I even start thinking that maybe I shouldn't
have applied the patch for changing the title, because the time spent on
this issue could have been better spent on something else.

I'd rather remove 10 lines to set the title than add 250 lines to restore
the title.

Just imagine that you know nothing about mc and you are reading the help.
Would you understand what this is about?  I can imagine that some users
would be confused and will blame unrelated problems on the "incorrect
delay".  I can imagine users writing a wrapper around mc to set the
timeout correctly if they log in remotely.  Yet the same users will close
mc together with the terminal without ever needing the saved title.

It used to be "Thank you for using GNU Midnight Commander" in 4.5.55.
Too long for my taste.

I think that if you expect the audience of the patch (i.e.  those who
really care about the title after they exit mc) to edit $HOME/.mc/ini
and/or give command line options when running mc remotely, then probably
the same users won't have any problem adding something like this to the

PROMPT_COMMAND='echo -ne "\033]0;${USER} ${HOSTNAME%% *}:${PWD/#$HOME/~}\007"'

It's standard in Red Hat 8.0 and it sets the title after every command,
not just mc.
