Thank you for the report.
To summarize, with zgrep-1.6, this erroneously prints matches only
from the first file:
$ zgrep -f <(echo .) <(echo a) <(echo b)
/dev/fd/12:a
However, with the latest from git (and soon to be gzip-1.7), this now
works as desired:
$ zgrep -f <(echo .) <(echo a) <(echo b)
/dev/fd/12:a
/dev/fd/13:b
I see there is no NEWS entry for this fix and haven't yet identified
the origin of the bug or the commit that fixed it, but will do so.
Draft gzip 1.7 doesn't work for me (Fedora 23 x86-64). I have worked on
a patch but don't have a reliable fix yet, or even a portable test case
to illustrate the bug. Perhaps we should just think of it as a known bug
for now.
