Hmm, this assert in fill_buffer() does seem to be triggered by the "seek 
by reading forward" code (that was present long before my patch the other 
day, but only used for nonseekable streams). As far as I can see, it can 
be fixed in two ways:

- Remove the assert from fill_buffer(), since we have another use case 
where that isn't true (also, reading the code of fill_buffer(), the assert 
doesn't really seem right)
- Set s->buf_ptr = s->buf_end; before calling fill_buffer() in url_fseek

Michael, which way do you think this should be fixed?
