[httperf] Request Headers

It turns out the problem was me. The add-header parameter was using a
minus character (−  or U+2212) instead of a proper dash. You can
actually see it in that examples I gave but it's only barely
noticeable. My mistake was copying and pasting "−−add−header" from the
pdf manual.

−−add−header BAD
--add-header GOOD

In any case, thanks for the quick response and sorry for the silly
error on my part!

My guess at this point is (perhaps) our systems are picking up different getopt_long functions, and for some reason your's isn't working in the expected way.  But since I can't replicate the problem you are seeing, you'll have to dig into that yourself.
