Version Control With Subversion Source

Fix some minor capitalization and punctuation issues.

More minor tag tweaks for still more consistency.

Tiny tweak for consistency with similar sections.

* src/en/book/ch09.xml
Move misplaced Subcommands intro text. Tweak/add Options intro texts.

* src/en/book/ch09-reference.xml
Use common Subcommands sub-section intro text. Fix a command-in-title markup bit.

* src/en/book/ch09-reference.xml
* src/en/book/appb-svn-for-cvs-users.xml
* src/en/book/ch05-repository-admin.xml
* src/en/book/ch06-server-configuration.xml
Consistify! Refer to 'dump file' or 'dump stream', not 'dumpfile'
or 'dumpstream'. And wrap instances of stdin, stdout, and stderr
with <filename> tags (instead of a mix of filename, literal, and
emphasis tags).

Various fixes found while porting copyedit changes to ORA's tree.
This also includes a revert of the partial change to close up spaces
between footnote markers and preceding text, not because that change
was wrong, but because it was a tip-of-the-iceburg approach.
Consistency is easier to automate around.

Thanks to C-Mike for catching my misinterpretation of the
copyediting--the copyeditor wanted me to close up the space between
the punctuation mark and the footnote mark, *not* put the footnote
mark *before* the punctuation mark.

* src/en/book/ch09-reference.xml, src/en/book/ch02-basic-usage.xml:
Puncto-move-o.

Second round of copyedits for chapter 9, part 3 of 3.

Done. *whew*

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

* www/index.de.html: Fix various validation errors.
