I'm using GNU sed 3.02 recompiled for Win32.

I'd like to write a sed script that removes all Received: headers from
a mail message in a file.  It should work with headers that span 0..N
lines.  I spent some time searching the web and DejaGoogle today and
didn't find anything that does what I want or imparted enough of a
clue for me to figure it out.

I've just started using sed, so if my current attempt looks idiotic,
that's why.

Here's the script I've written.

/^Received:.*/{
:START
d
n
/^[[:space:]].*/{b START}
}

I think that it should do the following:

if matches expression "^Received:.*"
	delete the current line
	read in the next line
	if matches expression "^[[:space:]].*"
		go to START
	else
		output current line

The actual result is that it strips the first line of a multiline
Received header, but leaves any subsequent lines belonging to that
header.  I've probably been staring at it too long, but I can't see
what I'm doing wrongly.
