commit d212bdc40096fde87b086290ac34b1cc6517b19f Author: Takashi Yano via Cygwin-patches <[email protected]> Date: Sun May 31 14:53:20 2020 +0900 Cygwin: pty: Revise the code which prevents undesired window title. - In current pty, the window title can not be set from non-cygwin program due to the code which prevents overwriting the window title to "cygwin-console-helper.exe" in fhandler_pty_master::pty_ master_fwd_thread(). This patch fixes the issue.
