+Subject: [PATCH 55/N] Cygwin: console: Set ENABLE_PROCESSED_INPUT when
+ disable_master_thread
+
+Currently, ENABLE_PROCESSED_INPUT is set in set_input_mode() if
+master_thread_suspended is true. This enables Ctrl-C handling when
+cons_master_thread is suspended, since Ctrl-C is normally handled
+by cons_master_thread.
+However, when disable_master_thread is true, ENABLE_PROCESSED_INPUT
+is not set, even though this also disables Ctrl-C handling in
+cons_master_thread. Due to this bug, the command
+  C:\cygwin64\bin\sleep 10 < NUL
+in the Command Prompt cannot be terminated with Ctrl-C.
+
+This patch addresses the issue by setting ENABLE_PROCESSED_INPUT
+when either disable_master_thread or master_thread_suspended is true.
+
+This bug also affects cases where non-Cygwin Git (Git for Windows)
+launches Cygwin SSH. In such cases, SSH also cannot be terminated
+with Ctrl-C.
+
+Addresses: https://github.com/git-for-windows/git/issues/5682#issuecomment-2995983695
+Fixes: 746c8116dd4f ("Cygwin: console: Allow pasting very long text input.")
