Fix "read more" flag From the most excellent angry donuts site: http://www.angrydonuts.com/the_nuisance_of_the_read_more_fl From author: Note that I'm using a lot of arguments to l() -- I'm telling it to provide an 'absolute' path, because these teasers often go out to RSS, and providing an absolute path is much, much safer.

./ed_readmore.module, line 73

Customize the "Read more" link shown in teasers.
