Proc ‘uniform-vector-read!’ is deprecated (ugh), and its implementation
rebased onto ‘(rnrs io ports) get-bytevector-n!’.  Unfortunately, there
seems to be a glitch in the arg shuffling.  Here is /tmp/foo.scm:

Attachment: foo.scm
Description: application/scheme

and here is a series of invocations that demonstrate the discrepency
between ‘get-bytevector-n!’ (ok) and ‘uniform-vector-read!’ (ko):

set -x ; guile --version ; guile -s foo.scm ; guile -s foo.scm ok ; guile -s 
foo.scm ko
+ guile --version

`uniform-vector-read!' is deprecated. Use `get-bytevector-n!' from
`(rnrs io ports)' instead.

FWIW, Guile 1.8.8 produces same output as ‘ok’ on a similar (sans the
‘use-modules’ and ‘uniform-vector-element-size’ noise) input, so i think
this situation is a regression.  Am i missing something?

As long as it wasn't _next_ release, I am happy to fix it.

Patch pushed. Closing.
