bug#18029: 24.4.50; bad shell-script-mode indentation due to ^[{([] in a here document

[Ian Kelling <ian@iankelling.org>]

emacs -Q the following files, then use indent region on the whole buffer:
(indent-region (point-min) (point-max)) Similar indent commands will work the
same. This is how they get indented:

#!/bin/bash
if true; then
    true <<'EOF'
[ line beginning with one of [{( 
EOF
fi

if true; then
    true
    # comment containing a single quote 'true
           fi
            true
            


The true commands could be other things, they are just an example. I assume the
if statements could be other things which create indents. The final fi and
anything beyond it get bad indenting that is determined by the quote in the
first quote from 'EOF' Another variation of this bug:


#!/bin/bash
if true; then
    true <<EOF
[ line beginning with one of [{( 
EOF
fi

if true; then
    true
    # comment containing a single quote 'true
                                        fi
                                         true
                                         

The final fi and beyond's indenting is determined by the quote in 'true.
