+Bug-Description:
+
+Bash-4.2 does not attempt to save the shell history on receipt of a
+terminating signal that is handled synchronously. Unfortunately, the
+`close' button on most X11 terminal emulators sends SIGHUP, which
+kills the shell.
+
+This is a very small patch to save the history in the case that an
+interactive shell receives a SIGHUP or SIGTERM while in readline and
+reading a command.
+
+The next version of bash will do this differently.
