Imagine you do

    cat > /tmp/foo <<EOF
foo
bar
EOF

The cat line is indented because of a surrounding if, or something.
Further imagine you reindent and then Emacs changes this to

    cat > /tmp/foo <<EOF
    foo
    bar
    EOF

Then you'll see two things happening.  The first is that the file
contents of /tmp/foo have suddenly changed -- it contains eight spaces
more than it used to.

Secondly, it might happen that the shell script doesn't run at all
because the shell is looking for "EOF" at the beginning of a line.
But I'm not sure about this, and I'm too lazy to check at the moment.

I'm happy that Emacs does not indent the here documents.
