question about window package

[eric at seismo.UUCP]

Does the window package allocate memory for the entire buffer  area.  Or
does it allocate memory for 'real' text only, intuiting  where  trailing
'virtual' spaces are from the length of real text on a  line.  It  seems
that the latter is essential if the package is to be used in any  screen
editor-like application with a reasonable maximum line length.  (If  the
former, with a 1K maximum  line  length,  a  5000  line  file  takes  10
megabytes (16 bits per char, remember)).
