That's a better idea than omitting the document environment as you've
suggested in your other mail.

Some comments:

  - The \documentclass macro doesn't need to start a line.

  - A commented \documentclass shouldn't prevent it being inserted.

  - The regex is a bit too lax, e.g., maybe someone has a
    \documentclasssetup, which would also be matched by your regex.

You might want to have a look at `LaTeX-current-environment' wrt. the
comment stuff.
