This is hard to avoid, since skipping the more prompt would mean that you actually will miss the first line of the ATTENTION message, which is going to scroll off-screen. But the dialog prompt should appear, since we wait for the user to enter a key. Hmm, this is a bit tricky, since aborting the message when 'q' is hit is at quite a low level. The simplest solution that I see is to disable the effect of quitting at the more prompt for the dialog message. I don't see a reason why one would want to quit for such a short message. And the dialog itself allows quitting with CTRL-C or . OK, I have made a patch for it. Hopefully it's all really fixed now! Patch 5.4.19 Problem: In a terminal with 25 lines, there is a more prompt after the ATTENTION message. When hitting 'q' here the dialog prompt doesn't appear and file loading is interrupted. (Will Day) Solution: Don't allow quitting the printing of a message for the dialog prompt. Added the msg_noquit_more flag for this.
