plz optionally decodes response bodies according to the content-type 
header, depending on the :decode argument (although Joseph found a bug 
in the implementation of that, and I'll merge his fix soon).  plz does 
not do anything else, e.g. setting a buffer's coding system variables. 
If :decode is nil, plz does no decoding and leaves it to the user.

For HTML, with its potential for having a META tag that may also specify 
encoding, that would be up to the user; plz offers no special support 
for various content types.

If a user wants to handle these issues manually, the ":as 'response" 
argument to plz should be used, which allows the user to process the 
response headers and body directly.
