Subject: [PATCH] minimal/do: some shells return error in "read x <file" for
 empty files.

...or files that contain bytes but not a trailing newline.  It's okay if we
don't get any data, but we definitely have to *not* let "set -e" abort us.
Now that we fixed set -e in the previous patch, it revealed this problem.
