Morphisms: Structure of finite maps
A finite map of affine schemes becomes, after a finite locally
free base change, the composition of a closed immersion by a
morphism Y --> X where Y is a union of closed subschemes mapping
isomorphically to X. We use this to show that a nowhere dense
set is mapped to a nowhere dense set by a finite morphism.
We also add an example that shows that a non-quasi-separated
quasi-finite morphism does not become finite after localizing
around a generic point of the target.
