Subject: gh-154525: Fix curses getcchar() failure on ncurses older than 6.3 (GH-154526)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aad438b0b61206ff67f32aa1ca24792f26f6fff9;p=thirdparty%2FPython%2Fcpython.git

gh-154525: Fix curses getcchar() failure on ncurses older than 6.3 (GH-154526)

getcchar() rejected a non-NULL opts argument before ncurses 6.3, so read
the color pair through the short slot instead.
