Hmm, I thought we turned off SIGPIPE when writing to filters these days.
Looks like we still complain if we get EPIPE, though. I feel like it
should be the filter's business whether it wants to consume all of the
input or not[1], and we should only be checking its exit status.

[1] As a practical example, consider a file format that has a lot of
    cruft at the end. The clean filter would want to read only to the
    start of the cruft, and then stop for reasons of efficiency.
