From 386289bdc8461898b05f318b77e0bedf2509537d Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Thu, 11 Nov 2021 16:55:11 +0200 Subject: [PATCH] Fix 8-color PuTTY -nw sessions broken by a recent commit * src/term.c (init_tty): Fix the change which introduced support for the terminfo Tc flag. The code as installed broke colors in PuTTY -nw sessions, because 'tigetflag' returned -1, which is non-zero, so it was treated as the sign that true color is supported. But if the value returned by 'tigetflag' is -1, it means the capability is not a boolean one, so that's not to be used as a valid support for 24-bit color.
