When utility buffers were introduced for file2str read
requests, a subtle change was inadvertently introduced
such that a read of zero no longer returns a -1 value.
This commit ensures that zero bytes read returns a -1.
And although the solution differs from a merge request
submitted by sergey.senozhatsky@gmail.com, a thank you
is offered for revealing this potential abend problem.

HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
