Avoid "broken pipe" message

Question

Is there a way to avoid this message in a command like the following?

tac myfile | sed '/abc/q'

I understand why the message occurs: sed exits when it finds 'abc' and tac has no where else to send its data. But I would like a way to tell Bash "it's OK, I expect this to happen."

Disabling SIGPIPE should do it:

trap -- '' PIPE
