Minor changes to FILL documentation to conform to style guide:
* Upper-case a usage of the command name.
* Move explanatory comment in examples from code listing to surrounding paragraph.

Improve the grouping of sentences into paragraphs

* First sentence referred to DISTANCE, not DISTANCEXYZ
* Second example did not include DISTANCEXYZ
