Comment (by cmbarton):

 * could it ask for the datum transform before getting to the summary page?
 the summary page still lists the +dx +dy +dz proj4 terms which will not be
 used.


 Question, is there any '''harm''' in including +dx=0 +dy=0 terms when
 other information about transforms is also included? The reason is that
 the proj4 string is being built by accretion of information out of the
 datums.table and ellipse.table, and then any datum transforms are being
 included using the datatrans= argument for g.proj.

 So does +dx=0, etc. need to be filtered out?
