curses: message window border w/ align_status:left

This fixes the missing message window border when restoring with
align_status:left (which narrows and forces that window to the right).
It can't possibly be the correct way to fix things but does work.

This was not a problem with 3.6.4 (the most recent pre-3.7 playground
I have on hand) but I don't have the energy to use 'git bisect' to
track done when it started to whether the cause is discernable.  The
message history is put into place without going through putstr() so
differs from normal message handling.
