* en/book/ch05-repository-admin.xml
Update the screen output for 'svnsync help copy-revprops'.

Merge from ^/trunk/en r4066, adjusting as necessary for applicability
to the 1.6 version of this text.

Finish issue #140 ("ch05: svnsync walkthrough refers heavily to
CollabNet's Subversion repository ... which is no more.")

* en/book/ch05-repository-admin.xml
Rework svnsync examples to use the book's source repository instead
of the now-defunct svn.collab.net Subversion source code repository.

Finish issue #138 ("1.7 change: error and warning number codes now
reported").

* en/book/ch02-basic-usage.xml,
* en/book/ch03-advanced-topics.xml,
* en/book/ch07-customizing-svn.xml,
* en/book/ch09-reference.xml
Retroactively discover and insert error codes into error messages
and warnings (updating error messages which have changed).

Finish issue #146 ("1.7 change: Permanent HTTP redirects are
automatically followed.").

* en/book/ch04-branching-and-merging.xml
Add a note about using permanent redirects to give clients a clue
about a repository's new location, and point out that 1.7 clients
will automatically relocate working copies when they see such
things.

Merge from ^/trunk/en r4062, which fixed issue #89 ("ch09: svn
options: --strict, --targets & switch").
