[Patch] gzip_disable broken without pcre and with multiple arguments

[Derrick Petzold]

Hello,

I found a couple of minor bugs with gzip_disable.

     *If built without the pcre library the gzip_disable_msie6 flag
was uninitialized
      resulting in the flag not being evaluated causing gzip responses
to be sent to msie6 agents.

     *This is very minor as it only affects an undocumented feature.
When setting mutliple
       arguments to gzip_disable:

           gzip_disable ""MSIE [1-6]\." "Python";

       any arguments after the first were broken.

the patches are attached.

Regards,
  Derrick
