Thanks for the pointer.  That discussion points
to some alternative fixes that may be more useful
(instead of installing a repaired shell).

One approach is to install a trap for SIGPIPE in
non-terminating command in a pipeline where the
later items might not process all the data, e.g.:
   (trap {} SIGPIPE; find .) | head -1

THIS IS A REALLY, REALLY BAD DECISION BY THE BASH TEAM.
Why should the default be "create annoying spurious error report?".
This should at least be a run-time settable option,
with the OPPOSITE default.

Which is sad, bash is generally reasonably good.
I guess now I have to say "bash, once properly configured
using DONT_REPORT_SIGPIPE, is reasonably good."
