(I'm going through old bug reports that unfortunately got no response at
the time.)

Test case:

echo <<EOF
# foo bar
EOF

`M-q' on the # line, and you get:

echo <<EOF
# foo bar EOF

Which is certainly odd, but...

echo foo
echo foo
echo foo

M-q on that and you get

echo foo echo foo echo foo

That is, it's not clear that `M-q' in shell mode is that well defined,
and what it does in EOF sections isn't inconsistent with what it does
elsewhere...

Anybody got an opinion?
