+k rather than the preferred +k_0 may be an artifact that I left in the USGS
distribution. I will have to check.
The "+unfact" option *is not* of my doing and comes from some non-USGS
distribution. I'm mystified and curious of its purpose.
Since I see "m." I suppose it is a product of the GRASS people.
As some may be unaware, I authored the original PROJ.4 as distributed
by the USGS kai.er.usgs.gov site.
