commit 7c067a5508a2e92dcaaa52734e8c3051590ff85c Author: Takashi Yano <[email protected]> Date: Wed Dec 10 10:01:24 2025 +0900 Cygwin: pty: Fix ESC sequence parsing in pty_master_fwd_thread This patch fixes the bug in ESC sequence parser for title set used when pseudo console is enabled in pty_master_fwd_thread(). Previously, if multiple ESC sequences exist in a fowarding chunk, the later one might not be processed appropriately. Fixes: 10d083c745dd ("Cygwin: pty: Inherit typeahead data between two input pipes.")
