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

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

Bug-Reported-by:        Doug McMahon <[email protected]>
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.

Patch (apply with `patch -p0'):
