A source "command|" in /etc/Muttrc prevents screen's altscreen from working

[adeodato]

Okay, I don't know who is at fault here, and if there's a fix possible within mutt, but having a source "command|" statement in /etc/Muttrc makes screen's altscreen feature not work. Note that having such source command in ~/.muttrc does not exhibit the problem.

To reproduce:

% echo altscreen on >screenrc
% echo 'source "/bin/echo|"' >>/etc/Muttrc
% screen -c screenrc
% clear
% mutt
q

When quitting mutt, the prompt will be at the bottom of the window, instead of the top.

Umm, this works here. A 'source|' from the system config by no means different then ser config, except that it gets parsed earlier. Also, when do clear the screen, what do expect to see if you clear the screen before running mutt?

The difference is that, outside screen, or in a screen without "source |"
in Muttrc, if you run and quit mutt right after invoking "clear", you see:

  hostname% mutt
  Mailbox is unchanged.
  hostname%

OTOH, inside screen in a 24-line terminal I'm seeing:

  hostname% mutt






















  Mailbox is unchanged.
  hostname%


That is, lots of empty line in the middle.
