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

Bash-Release: 4.0
Patch-ID: bash40-022

Bug-Reported-by:  Bernd Eggink <address@hidden>
Bug-Reference-ID: <address@hidden>
Bug-Reference-URL: 
http://lists.gnu.org/archive/html/bug-bash/2009-04/msg00118.html

Bug-Description:

When parsing case statements in command substitutions, the shell did not
note that a newline is a shell metacharacter and can legally be followed
by a reserved word (e.g., `esac').

Patch:
