+ retcode = read(fd, ptr, size * nmemb) * size;


+ return fwrite(ptr,size,nmemb,stream) * size;

Sorry, but these changes are incorrect (and it seems they all are of the same
kind). The return code (for both read and write callbacks) should be the
amount of data they have taken care of, which is exactly what read() and
fwrite() etc typically already return. The day we'd change 'size' to be
something else than 1 when passed to the callback, your changes would make the
examples return that amount multiplied a value and if that value isn't 1 the
return code is plain wrong.

Your man page patch looks fine and I'll commit it soon.
