From d0a2a85de3849455822ea072b87190ed5ea99d0b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 23 Apr 2018 00:24:29 +0200 Subject: [PATCH] mingw: really handle SIGINT Previously, we did not install any handler for Ctrl+C, but now we really want to because the MSYS2 runtime learned the trick to call the ConsoleCtrlHandler when Ctrl+C was pressed. With this, hitting Ctrl+C while `git log` is running will only terminate the Git process, but not the pager. This finally matches the behavior on Linux and on macOS.
