Hi,

I'm looking into reference implementation and have noticed that
there are signature mismatches. I'm listing ones I've found below:

- gconcatenate
   The SRFI says this takes one argument of Generator generator but
   the reference implementation takes arbitrary length arguments.

- gmerge, gunion, gintersection, gmap
   The SRFI says this requires at least 2 arguments but the reference
   implementation requires only one (comparator).

- gfold
   The SRFI says this requires at least 3 arguments but the reference
   implementation requires only two (comparator and seed).

- gfilter-map
   The SRFI says this requires at least 2 arguments but the reference
   implementation requires only one (proc).

And gdelete-neighbor-dups takes procedure as its optional argument but
other procedures such as gmerge or gunion takes comparator. Should it
be a comparator for consistency? (Though it's also mentioned in the
comment.) Or others should accept procedures instead of comparators?

Cheers,
