Comment (by novoselt):

 OK, how about this variant:
  * class method `PointCollection.output_format` that affects both text and
 LaTeX representation and is visible to those who will look at TAB-
 completion;
  * default text representation as described above, with line breaks and
 coordinate alignment;
  * default LaTeX representation as a tuple (i.e. as it was but with
 lattice subscript) - aligning coordinates which are wrapped in \left( and
 \right) it a bit hard, those who want alignment are welcome to switch to
 matrices.

 The new patch does all this and fixes all doctests in `point_collection`
 module so they show how it works now. If you are OK with this look and
 approach, I'll fix doctest formatting in all other files.
