[Qemu-devel] [PULL 4/6] ui/gtk: Fix non-working DELETE key

[Gerd Hoffmann <kraxel@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

GTK generates key events for the delete key with key->string[0] = 0x7f
... but this does not work right with the readline_handle_byte()
function in util/readline.c, since this treats the keycode 127 as
backspace. So let's add a special case for the GTK delete key to make
this key behave right in the monitor interface of the GTK ui.
