I suppose that migh work about as well as grammer checking in a word processor.
It has benefits - and dangers, especially if the organization around pushes for compliance; then the result is often bad prose.

Good programming is (as writing) about well structured thinking.
Automatic checking might help having details well documented.

But the kind of code commenting and documentation I have in mind,
which helps the programmer to structure his thoughts and vision,
and also increases code maintainability,
can only be encouraged by human help.

EDIT :
I answered before reading your links.
Good !
Any structure that helps us humans
communicate efficiently,
helps here !
