123	log_format doesn't allow logging of HTTP headers with a dash	pepello -	somebody	"Hi,

I've hit a bug in this awesome software. I'm trying to log some headers that our upstream generates, their name have a dash '-' in the middle, but log_format directive ignores all after the first dash in '$sent_http_'.

When you set a log format like this (trying to log Content-Length header, but any header-with-a-dash):

log_format  lenght    '""$sent_http_Content-Length""';

This is logged:

""--Length""

This is reproducible with all the versions available: 1.0.13, 1.1.16 and 0.8.55, too sorry I'm not able to fix it :-(

Thanks!"	defect	closed	major		nginx-core	1.1.x	invalid	log_format sent_http dash		Linux desa3 2.6.18-274.17.1.el5.centos.plusxen #1 SMP Wed Jan 11 11:44:32 EST 2012 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.0.12
