Yes, that patch looks fine. I shall apply it and commit a new version
of libcurses tonight.

This is very weird behaviour - I assume they do this to work around
some curses libraries not having a resizeterm function. Is there any
config option to use resizeterm?

>(i.e. overwrite a lot of global variables) that newterm() might not be
pretty much right. The initscr call is only supposed to be called
once to initialise curses - this function used to set up a whole swag
of globals to hold the curses internal state. These days initscr is
just a wrapper call to newterm(). The function newterm() allows an
application to talk to multiple, possibly different, terminals at the
