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

Bash-Release:   4.3
Patch-ID:       bash43-034

Bug-Reported-by:        Dreamcat4 <address@hidden>
Bug-Reference-ID:       <address@hidden>
Bug-Reference-URL:      
http://lists.gnu.org/archive/html/bug-bash/2015-05/msg00001.html

Bug-Description:

If neither the -f nor -v options is supplied to unset, and a name argument is
found to be a function and unset, subsequent name arguments are not treated as
variables before attempting to unset a function by that name.

Patch (apply with `patch -p0'):
