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

Bash-Release: 4.0
Patch-ID: bash40-024

Bug-Reported-by:  Matt Zyzik <matt.zyzik@nyu.edu>
Bug-Reference-ID:  <20090405205428.4FDEA1C7175@ice.filescope.com>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2009-04/msg00021.html

Bug-Description:

When using the ** globbing operator, bash will incorrectly add an extra
directory name when the preceding directory name ends with `*' or an empty
string when there is no preceding directory name.

Patch:
