Ensure that cat works with any of the options, -A -v -e -E -T,
when applied to files in /proc and /sys, even when the FIONREAD
ioctl produces nonsensical results. Before this change, cat would
produce no output (or truncated output), for some linux kernels.
* src/cat.c (write_pending): New function, factored out of cat.
(cat): Also interpret a negative ioctl/FIONREAD count as indicating
that there are bytes to read. Some versions of linux-2.6.16 do that.
Write any pending output before returning.
Reported by Dan Jacobson in <http://bugs.debian.org/370583>.
* NEWS: Mention this bug fix.
* tests/misc/cat-proc: New file. Test for the above.
* tests/misc/Makefile.am (TESTS): Add cat-proc.
