Thanks. To summarize the discussion, here is what I ended up with.

Subject: [PATCH] sane_grep: pass "-a" if grep accepts it
Newer versions of GNU grep is reported to be pickier when we feed a
non-ASCII input and break some Porcelain scripts. As we know we do
not feed random binary file to our own sane_grep wrapper, allow us
to always pass "-a" by setting SANE_TEXT_GREP=-a Makefile variable
to work it around.
