I've used TAKE|CHOP|JUXTAPOSE instead of DUP to copy headers
conditionally. With more than one, though, that takes a separate
pipeline for each header record:
*: | h1: take 1 | h1dup: juxtapose | join * , , | all: fanin | *:
/ h1: | h2: take 1 | h2dup: juxtapose | join * , , | all:
/ h2: | top: take 4 | h1chop: chop 0 | h1dup:
/ h1chop: | h2chop: chop 0 | h2dup:
/ h2chop: | join * , , | all:
/ top: | join 3 , , | all:
