[MKDoc-modules] MKDoc::Apache_Cache always returns gzip encoded content

[Bruno Postle]

If I fetch a document served by MKDoc::Apache_Cache it returns gzip
encoded content regardless of the 'Accept-Encoding' header:

  ab -n1 -v4 -H 'Accept-Encoding: none' http://www.example.com/
  ab -n1 -v4 -H 'Accept-Encoding: gzip' http://www.example.com/

This is because of a bogus comparision of the http status code which
is always going to fail.

This fixes it for me:

<     lc $ENV{'HTTP_ACCEPT_ENCODING'} !~ /gzip/ and
<           $ret =~ /\ncontent-encoding\: gzip/ and do {
---
>     lc $ENV{'HTTP_ACCEPT_ENCODING'} !~ /gzip/ and do {
