These definitions are automatically derived from the EPSG tables, and
I am not convinced that replacing stere with sterea would necessarily
match better in all cases.  Does EPSG use different projection 
methods codes for different kinds of stere?  If not it may be hard to
know where to apply what. 

I would add that similar issues apply for the description.

However, if the EPSG derived definitions are bad enough, and
you  can't reasonably fix things upstream, then you can submit
updated definitions for the coordinate systems in Bugzilla and
I will apply them. 

I *think* I have a way of managing "overrides" for the
autogenerated epsg file. 

Hmm, now that I look around, I don't know how I do this.
Perhaps I never did implement an override mechanism in
the generation code.
