Several things in Chapter 9, thanks to a great tech review from Karl
Heinz Marbaise (khmarbaise@...):

- Fix typo

- Remove unnecessary abbrev for --revision in --record-only doc

* src/en/book/ch09-reference.xml: Fixes.

Lose the 'Subversion's Features' section.

Move 'svndumpfilter' mention down in the list (it's less essential).

* src/en/book/ch00-preface.xml
s/BerkeleyDB/Berkeley DB/. Lose a bunch <quote> tags. Don't refer
to svn:externals as a feature (it's an implementation; "externals
definitions" is the feature).

Fix some long lines.

Finish trac ticket #118.

* src/en/book/ch07-customizing-svn.xml
Use Python instead of Bourne shell for the diff wrappers, and
annotating the Windows wrappers to note that using 'svn diff -x'
messes stuff up.

* src/en/book/ch03-advanced-topics.xml
Don't refer to "older Macintosh platforms" with regards to the CR
EOL marker.
