[sage-devel] Exceptions format; keyword 'implementation'

[Jori Mäntysalo]

1) Should we raise ValueError("Bad things happened.") or ValueError("bad 
things happened")? There are 3559 error of the former form and 4150 of the 
latter.

2) raise("Must be over a Numberfield or a Numberfield Order") in
src/sage/schemes/projective/projective_point.py should be corrected.
3) Should we use keyword "algorithm" or "implementation"? Or have both 
with different meaning?
