Try to use L/K notation for field extensions
We could also try to consistenly use "field extension" and not just
"extension" and consistently use "ring extension", etc.

LaTeX: \Spec
Introduced the macro
\def\Spec{\mathop{\rm Spec}}
and changed all the occurences of \text{Spec} into \Spec.

Etale local structure finite type morphisms (bis)
Small improvement. There seems to be no way of making this lemma
appear more natural. The earlier statements on the behaviour of
the number of geometric irreducible components are in some sense
much easier to grok. Even the addendum of obtaining affine etale
neighbourhoods on which the stated properties are true seems
tricky whereas staring at the diagram for a bit easily
convinces one that it has to be true.
Of course, using the lemma is much more fun than actually
proving this lemma in detail.
More improvements welcome!
