Release Status: release

Description:
Doing an indented "cat <<- !" (tested with other terminators also) 
fails as shown in the scripts below.

Repeat-By:

Here are two scripts that demonstrate the problem, in two different 
ways.

--------------------------------------------------------------------
#!/bin/bash

case $1
in
    a)  cat <<- !
        By itself, this works fine.
        !
                
        [ 1 ] && {
            cat <<- !
            This bang breaks it. Moving it to BOL, or even one tab 
            back, fixes the problem.
            !
        }
        ;;

    b)  cat <<- !
        This one also works once that second bang is "fixed".
        !
        ;;
esac
--------------------------------------------------------------------

--------------------------------------------------------------------
#!/bin/bash

while [ 1 ]
do
        cat <<- !
        By itself, this works fine.
        !
                
            cat <<- !
            This bang breaks it. Moving it to BOL, or even one tab 
            back, fixes the problem.
            !
done
--------------------------------------------------------------------

In both cases, the shell fails to read the terminator.
