We are not currently saving & restoring the title by ourselves, so it 
sounds like iTerm2 on Mac is behaves differently from vte on Linux in this 
respect...

Maybe we could do something along the following lines; I haven't even 
checked whether this compiles, but what it should do is to push the last 
title on the stack the first time it is updated, and the pop it out upon 
exiting mc.

I don't know if iTerm2 fully supports the title stack feature, but it has 
the potential to work; if you don't want to patch mc, you can try wrapping 
the call with

    echo -ne '\e[22t'
    mc
    echo -ne '\e[23t'

If that works, would be nice if you could create a nice feature request on 
Trac with all relevant info or maybe even prepare a clean patch?
