* In historical vi, O_VERBOSE didn't exist, and O_TERSE made the error
* messages shorter. In this implementation, O_TERSE has no effect and
* O_VERBOSE results in informational displays about common errors for
* M_BERR Error: M_ERR if O_VERBOSE, else bell.
* M_ERR Error: Display in inverse video.
* M_INFO Info: Display in normal video.
* M_SYSERR Error: M_ERR, using strerror(3) message.
* M_VINFO Info: M_INFO if O_VERBOSE, else ignore.
