I cannot tell from reading the April 1995 draft, whether or not an
input iterator can be dereferenced mulitple times.  Can it?

Thanks,

The short answer is yes.

The long answer is, that was one of many questions about input
iterators that was cleared up at the Tokyo meeting in November '95.
Input iterators are queer birds, and using them (or writing them)
safely requires careful study of the requirements table and all
the associated notes.  The April '95 draft is lacking some of these
notes.
