ncurses 6.2 - patch
20201031
+ modify MKterm.h.in so that it is not necessary to include <curses.h>
before <term.h> (prompted by discussion with Reuben Thomas).
+ review/improve synopsis for curs_sp_funcs.3x (prompted by discussion
with Reuben Thomas).
+ improve format of output in tic's check_infotocap() function, to
ensure that the messages contain only printable text.
+ modify configure-check for clang to verify that -Qunused-arguments
is supported. IBM's xlclang does not support it (report by Steven
Pitman).
needed in to tic's use-resolution when pad_char is cancelled
