Even if your proposal solve the issue, I have a question of what's 
append in the two different cases.

I use the same sequence (1/ cd ztry 2/ launch emacs ("emacs &" or "emacs 
 > /dev/null 2>&1 &" 3/ cd .. 4/ exit emacs 5/ newline 6/ ^D) with 
mintty configure for logs.

The log for the first case (mintty1459.log) is strongly longer that the 
second one (mintty1470.log). It look like the wall window content is 
rewritten each time a line is added.

I would appreciate if someone can give me some explanation. It look like 
that I have the same kind of behavior with other program (i.e. scala 
repl or sbt)

Thanks
