`call-process-region' is stuck in the past

Here's what happens:
 
I switch to some buffer containing some arbitrary HTML code.  
I evaluate the following form, which is designed to render
this HTML:

 (call-process-region (point-min) (point-max) "tcsh" nil
                      (get-buffer-create "*foo*")
                      nil "-c" "lynx -dump")

I switch to the buffer *foo* and I see (to my annoyance):

This is not what I expected to see, because, as stated above,
the buffer that I ran this process on had arbitrary HTML code
that has *nothing to do* with the output seen here.

I did in fact use 'lynx -dump' to generate output that looked
like this some time ago, but since the I've used it to generate
lots and lots of different kinds of output. 

The weird thing about it is that I've restarted Emacs in the
mean time, and I don't even see any files hanging around 
any of my working/nearby directories with the HTML code to
generate the above output.  I have no idea where 'lynx -dump'
is getting the info from.  If I run it under a shell or even
as a `shell-command' on a file or URL from within Emacs, it
produces the output I'd expect!  So, I figure, there must
be something weird going on with `call-process-region' but
I'm not sure what could be going on. 

Skimming the code, it says that some temporary files are used,
but I don't know where to look for these files.  Please
help!  This is too weird!
