Bug-Reported-by:  Bernd Eggink <monoped@sudrala.de>

http://lists.gnu.org/archive/html/bug-bash/2009-04/msg00118.html

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').
