Maybe we can check the whole VC_LIST, there are only a few files that
start with an empty line (typically README.txt) and those can have an
exception. But there are some that shouldn't start with an empty line, e.g.:
docs/generic.css:1:
src/locking/lockd.conf:1:
src/locking/sanlock.conf:1:
and some testdata under
tests/nodeinfodata/linux-test3/node/node*/meminfo. These in particular
should be plain copy of their origins in sysfs which at least on my
system doesn't start with an empty line:
# head -n1 /sys/devices/system/node/node0/meminfo
Node 0 MemTotal: 4004132 kB
But your version is good too. ACK whether you decide to change it the
way I'm suggesting or not.

The existing sc_prohibit_empty_lines_at_EOF in maint.mk does a similar
check but using perl instead of awk. But that shouldn't matter.

I'd use ALL of VC_LIST_EXCEPT (not just the .c and .h files). But in
general it looks like it does the right thing.

Yeah, but that is taken from gnulib, isn't it? Do you suggest
proposing this fix there?

why is this to stdout...
I wanted to simulate the behaviour of other syntax-check rules that
use grep without output redirection. No problem of making this go to
stderr, though.

Michal had a good point of those other files. I'll remove the grep,
add necessary files into except rule and fix all the other non-.[ch]
ones.
Thanks for the reviews
