In
that case, shouldn't EPSG definitions be modified, in order to use
+lon_0 instead of +pm ? For example, French Lambert projections are
defined with "+lon_0=0 +pm=paris". Wouldn't it be better to use simply
"+lon_0=2.33..." ? It would enable pj_inv, pj_fw and pj_transform to
return similar results.

Fabrice.
