Version Control With Subversion Source

Fix small inconsistencies in command line examples in the book.

* doc/book/book/appb.xml
(svn-ap-b-sect-1.2.2): Change 'svn cleanup working-copy' to just 'svn
cleanup' since the text says to run it from the top of the WC.

* doc/book/book/ch02.xml
(svn-ch-2-sect-3.1): Change 'ls -a' to 'ls -A' since . and .. are not
shown in the output.

* doc/book/book/ch03.xml
(svn-ch-3-sect-4): Change revision 3678 to revision 2499 to be
consistent with all the other examples.

* doc/book/book/ch04.xml
(svn-ch-4-sect-2.1): Change trunk/ to trunk because trailing slashes
are not used that way in other examples.
(svn-ch-4-sect-6.2): Remove . and .. from ls output (no -a was given).

Add a sentence to the svnadmin Subcommand Reference.

* doc/book/book/ch09.xml:
Explicitly state that svnadmin hotcopy is safe to run on a live repository
that is being accessed by other processes. The wording is taken almost
exactly from chapter 5.

Add a few missing mentions of first-column 'X' in the svn status output.
This fixes issue #1898.

* doc/book/book/ch03.xml
(svn-ch-3-sect-4.3.1): Add 'X' to example output of svn status.

* doc/book/book/ch09.xml:
(svn-ch-9-sect-1.2): Add 'X' to complete svn status reference.

Various documentation typos fixed.
