nginx 0.6.15
*) Feature: cygwin compatibility.
Thanks to Vladimir Kutakov.
*) Feature: the "merge_slashes" directive.
*) Feature: the "gzip_vary" directive.
*) Feature: the "server_tokens" directive.
*) Bugfix: nginx did not unescape URI in the "include" SSI command.
*) Bugfix: the segmentation fault was occurred on start or while
reconfiguration if variable was used in the "charset" or
"source_charset" directives.
*) Bugfix: nginx returned the 400 response on requests like
"GET http://www.domain.com HTTP/1.0".
Thanks to James Oakley.

again; bug appeared in 0.6.7.
