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?

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
same time.
