Kevin Wortman has contributed a fix to a bug in the
reference implementation for SRFI 121, and has done minor
refactoring, too.  John Cowan, one of the authors, has
approved this change, so I've published it on
<srfi.schemers.org>.

The diffs are here:

Kevin's description is here:

| Commit cd3f56f fixed a bug in generator->list, where the
| procedure could consume the wrong number of elements from
| the generator.  It turns out that generator->reverse-list
| has the same bug.  This patch fixes that.
>
| While we're at it, we replaced each of these problematic
| loops with a one-liner that reuses other procedures.  The
| old loops were not tail-recursive, so they allocated O(n)
| activation records. The new code avoids that so should
| perform better.

| Commit Summary
