This also fixes a regression recently added in PROJ master now that cs2cs is using underneath the new ISO19111 code to generate pipeline, which doesn't emit +no_defs, and thus cause issues with CRS using LCC_1SP projections that erroneously use the lat_2=45 default of proj_def.dat

Is this because we now don't have a default ellipsoid?

I guess that would leave many projections default-less with regards to ellipsoids. It seems to me that +proj=merc not working without adding +ellps=... is a step in the wrong direction. I think setting ellipsoid parameters for GRS80 when initialising a PJ would be a sane default. If +ellps=bessel (or whatever) is set it will obviously be overridden.

OK, default to ellps=GRS80 per 6bb14fa
