        !            56: .SH BUGS
        !            57: Software tabs using \fB^T\fR work only immediately after the
        !            58: .I autoindent.
        !            59: .PP
        !            60: Left and right shifts on intelligent terminals don't make use of
        !            61: insert and delete character operations in the terminal.
        !            62: .PP
        !            63: The
        !            64: .I wrapmargin
        !            65: option can be fooled since it looks at output columns when blanks are typed.
        !            66: If a long word passes through the margin and onto the next line without a 
        !            67: break, then the line won't be broken.
        !            68: .PP
        !            69: Insert/delete within a line can be slow if tabs are present on intelligent
        !            70: terminals, since the terminals need help in doing this correctly.
        !            71: .PP
        !            72: Saving text on deletes in the named buffers is somewhat inefficient.
        !            73: .PP
        !            74: The
        !            75: .I source
        !            76: command does not work when executed as \fB:source\fR;
        !            77: there is no way to use the \fB:append\fR, \fB:change\fR,
        !            78: and \fB:insert\fR commands, since it is not possible to give
        !            79: more than one line of input to a \fB:\fR escape.  To use these
        !            80: on a \fB:global\fR you must \fBQ\fR to \fIex\fR command mode,
        !            81: execute them, and then reenter the screen editor with
        !            82: .I vi
        !            83: or
        !            84: .I open.
