23 * In historical vi, O_VERBOSE didn't exist, and O_TERSE made the error
24 * messages shorter. In this implementation, O_TERSE has no effect and
25 * O_VERBOSE results in informational displays about common errors, for
28 * M_NONE Display to the user, no reformatting, no nothing.
30 * M_BERR Error: M_ERR if O_VERBOSE, else bell.
31 * M_ERR Error: Display in inverse video.
32 * M_INFO Info: Display in normal video.
33 * M_SYSERR Error: M_ERR, using strerror(3) message.
34 * M_VINFO Info: M_INFO if O_VERBOSE, else ignore.
36 * The underlying message display routines only need to know about M_NONE,
37 * M_ERR and M_INFO -- all the other message types are converted into one
38 * of them by the message routines.

44 * There are major problems with error messages being generated by routines
45 * preparing the screen to display error messages. It's possible for the
46 * editor to generate messages before we have a screen in which to display
47 * them, or during the transition between ex (and vi startup) and a true vi.
48 * There's a queue in the global area to hold them.
50 * If SC_EX/SC_VI is set, that's the mode that the editor is in. If the flag
51 * S_SCREEN_READY is set, that means that the screen is prepared to display
