nginx-0.3.50-RELEASE import

    *) Change: the "proxy_redirect_errors" and "fastcgi_redirect_errors"
       directives was renamed to the "proxy_intercept_errors" and
       "fastcgi_intercept_errors" directives.

    *) Feature: the ngx_http_charset_module supports the recoding from the
       single byte encodings to the UTF-8 encoding and back.

    *) Feature: the "X-Accel-Charset" response header line is supported in
       proxy and FastCGI mode.

    *) Bugfix: the "\" escape symbol in the "\"" and "\'" pairs in the SSI
       command was removed only if the command also has the "$" symbol.

    *) Bugfix: the "<!--" string might be added on some conditions in the
       SSI after inclusion.

    *) Bugfix: if the "Content-Length: 0" header line was in response, then
       in nonbuffered proxying mode the client connection was not closed.
