From ed454a217da417dc052723ea70da8efde0f2e66c Mon Sep 17 00:00:00 2001 From: Mark Nudelman Date: Sat, 10 Aug 2024 08:11:59 -0700 Subject: [PATCH] Fix bug related to ctrl-X when output is not a terminal. We should not check for ctrl-X input when the output is not a terminal. This results in trying to poll and read input characters from stdin instead of from the terminal. This problem existed in v661 so is not strictly a regression that needs to be addressed in the upcoming bug fix release, but because it's a low-risk fix and has potentially serious consequences, I'm including it.
