[GRASS-dev] problems with datum parameters tables

I'm working on the GUI location manager and have run into a couple of  
irregularities in a couple of the projections parameters files. I'm  
sending this to the list instead of keeping it in the location wizard  
track ticket because they are a more general issue that will affect  
projection/location creation by other means too.

In proj-parms.table, the entry for "GEOS" is incorrect. There should  
be 3 subentries for each entry: projection code, projection  
description, and required parameters. However, GEOS is missing the  
projection description.


The following entry has the correct format

GINS8:Ginsburg VIII (TsNIIGAiK):LAT0=ask,0.0;LON0=ask,20.0

GEOS is the only incorrect formatted entry in the file. It also is NOT  
in the datums.table file. So either it should be:

1) deleted from proj-parms.table, or
2) added to datums.table and a descriptive field added in proj- 

Because it cannot be correctly parsed, I'll just skip it in the GUI  
location wizard. But if we are going to use this projection, it needs  
to be corrected in the 2 tables.

Also, in the proj-desc.table, several entries are incorrectly  
formatted. None of them are used by the proj-parms.table and so they  
probably should be removed from the proj-desc.table file. All are  
missing their description fields that are needed so that they can be  
read by a user. They are:
