g.region should not duplicate the code of G3d_regionToCellHead ()

[1gray]

Currently, g.region/main.c includes almost the same code that's already available as the G3d_regionToCellHead () function.

Hence, I suggest the following change:

general/g.region/main.c (main): Use `G3d_regionToCellHead' instead of
copying the fields directly.

An (untested) patch is attached.

If it works, consider to submit. Folks often just test once present in SVN.
