_______________________________________________________
Details:
When the Edwin tutorial is invoked (i.e. C-h t), it builds text from
the TUTORIAL file by replacing the line that starts with << with a
number of newlines equal to the difference between the window's size
and four more than the point at which the << line starts. The intent
is that the first tutorial message should be presented at the bottom of
the window, but if it does not fit in the window the INSERT-NEWLINES
call receives a negative argument for the number of newlines, because
the code does not consider this case. 24 lines for the enclosing
terminal or X window do not suffice, so this problem is exhibited in
standard 80x24 terminals.
