+ add 'O' (wide-character panel test) in ncurses.c to demonstrate a
problem reported by Sadrul H Chowdhury with repainting parts of
a fullwidth cell.
+ modify slk_init() so that if there are preceding calls to
ripoffline(), those affect the available lines for soft-keys (adapted
from patch by Clive Nicolson).
+ document some portability issues in man/curs_getyx.3x
+ ignore --with-chtype=unsigned since unsigned is always added to
the type in curses.h; do the same for --with-mmask-t.
+ change warning regarding --enable-ext-colors and wide-character
in the configure script to an error.
+ tweak error message in CF_WITH_LIBTOOL to distinguish other programs
such as Darwin's libtool program (report by Michail Vidiassov)
+ modify edit_man.sh to allow for multiple substitutions per line.
+ set locale in misc/ncurses-config.in since it uses a range
+ change permissions libncurses++.a install (report by Michail
Vidiassov).
+ corrected length of temporary buffer in wide-character version
of set_field_buffer() (related to report by Bryan Christ).
