BASH PATCH REPORT
			     =================

Bash-Release:	4.2
Patch-ID:	bash42-008

Bug-Reported-by:	Doug McMahon <mc2man@optonline.net>
Bug-Reference-ID:	<1299441211.2535.11.camel@doug-XPS-M1330>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2011-03/msg00050.html

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.
