Fixed range reduction near (but not very near) medium-sized multiples
of pi/2 (1 line) and expand a comment about related magic (many lines).

The bug was essentially the same as for the +-pi/2 case (a mistranslated
mask), but was smaller so it only significantly affected multiples
starting near +-13*pi/2.  At least on amd64, for cosf() on all 2^32
float args, the bug caused 128 errors of >= 1 ulp, with a maximum error
of 1.2393 ulps.
