Version Control With Subversion Source

Write "URL" consistently in upper case, in the Book and in messages that
the user may see (mostly error messages and the output of "svn info").

Change "Url" and "url" to "URL" in user-visible strings.

Minor fixes to the book.

* doc/book/book/ch03.xml
Use consistent spacing in example shell prompts.
Fix name of option "--non-recursive".

* doc/book/book/ch08.xml
Fix use of "svn up" to "svn update". (From Larry Shatzer.)
Use <quote> instead of ""'s. (From Larry Shatzer.)
Use consistent spacing in example shell prompts.

* doc/book/TODO: add some extra notes.

Kill 'svnadmin createtxn'. Cruft today, gone tomorrow.

* subversion/svnadmin/main.c
(subcommand_createtxn): Buh-bye.
(cmd_table): Remove junk related to the 'createtxn' subcommand.

* subversion/tests/clients/cmdline/svnadmin_tests.py
(create_txn): Remove (there is no more 'createtxn').
(remove_txn): Remove (I dunno how to force the creation of a
dangling, uncommitted transaction).
(test_list): Lose references to removed tests.

* subversion/doc/book/book/ch05.xml
Try to get the svnadmin subcommands list back into sync with the app.

Applied patch by Vincent Lefèvre.

* doc/book/book/ch08.xml
Corrected grammar in the "Examples" section.

Improve the book Makefile so it updates when it should and doesn't when it
shouldn't. It was always updating book-html-chunk, and never updating the
embedded revision number.

* doc/book/Makefile
Re-check the output of "svnversion" every time, but only update version.xml
if the revision number has changed. (Previously version.xml was never
updated unless it had been deleted.)
Only rebuild book-html-chunk if it is older than its (main) source files.
(Previously it was re-built every time.)
The image files are now dependencies of most targets.

* doc/book/book/ch07.xml
Corrected grammar in the "Get the Source Code" section.

Clarify. Rinse. Repeat.

* ch04.xml: Added footnotes about copy/move being single repository
only, as well as info and an xref on --relocate.

Miscellaneous minor fixes to the book.

* doc/book/book/appa.xml
Option name for "non-recursive" is "-N" not "-n".
Output of "svn status" no longer begins with "_".

* doc/book/book/appc.xml
Apply "<command>" style to program name "tethereal".
Fix capitalisation.

* doc/book/book/ch02.xml
* doc/book/book/ch03.xml
* doc/book/book/ch06.xml
Fix capitalisation, punctuation, etc.

Working through my book TODO list:

- Documented how to use 'svn co' to restart an interrupted checkout.

- Documented new 'svn st' symbol for incomplete directories ("!")

- Mentioned that killing $EDITOR without saving changes gives the
option to abort a commit.

- Pointed out that 'svn rm URL URL URL [...]' is now a single commit.
Same with 'svn mkdir dir1 dir2 dir3 [...]'

- Clarified that 'svn copy/move' *only* works within a single
repository. cross-repository copying is a post-1.0 feature.

- Documented 'svn switch --relocate'.

- 'svn import' syntax changed. Updated everywhere.

- Clarified that 'svn st -u' only adds an asterisk; it does *not* make
the entire record reflect the repository's version of the file.

* doc/book/TODO: Remove done items. Switched them to past tense and
added them to the commit message above. Phear my mAd SKillz!!1!!
* doc/book/book/appc.xml: Tweaks.
* doc/book/book/ch05.xml: Tweaks.
* doc/book/book/ch08.xml: Tweaks.
