Ohh...
So it's the HP-UX shell's "echo" that is detecting the write failure
but setting errno to 2 rather than the 1 that gzip users would expect
from gunzip.
I'm considering testing only zero-vs-nonzero exit status in the
help-version tests of those wrappers on systems for which echo fails
that way. Otherwise, with all of gzip's wrappers depending on other
programs that do not fail with the gzip-package-expected status, we'd
see too many reports of these unrelated failures.
