[development] a couple things to discuss about base_path()

[Khalid B]

In http://drupal.org/node/13148#comment-78766 I mentioned that
base seems to work fine.

I like the "fix my links" approach, since it can be done whenever.
This could evolve
into a referenetial link checker (makes sure that the link exists).

This can be #4 (a contrib module), and can have more features as time goes
by.

Morbus, where are you?
