I think you need "| \" at the end of this line.  At least that's what I
usually do and it seems to work.

It is not generally necessary to put a backslash at the end of a line that
ends with | (in shell script).

But it *is* necessary in this special case!  So, you get the prize.
Note that this solves it as far as getting bash to be happy with it is
concerned.  When I get a chance, I need to see about how VIM feels about it.

Here's test case:

 $ nl << EOF | nl
test
this
EOF
     1       1  test
     2       2  this
$ nl << EOF |
nl
test
this
EOF

-bash5: syntax error: unexpected end of file
Status: 2
 $ nl << EOF | \
nl
test
this
EOF
     1       1  test
     2       2  this
 $
