Oops! Fix some typos ("&rt;" -> ">").

This fixes issue #259 (1.8 change: `svn info` now shows
repository-relative URLs).

Some examples specifically grep for "URL". Most of those now grep for
"^URL" so as not to distract from the larger point of those examples
with the additional "Relative URL" output line.

* en/book/ch03-advanced-topics.xml
* en/book/ch04-branching-and-merging.xml
* en/book/ref-svn.xml
Update uses of 'svn info' to consider the "Relative URL" output line.

Fix issue #261 - Wrong primary index terms in Basic Work Cycle

* en/book/ch02-basic-usage.xml
Fix the index terms in the conflict resolution subsections. (They
were suffering from a bad case of copyandpastitis.)

Reverting [r5070] & [r5071] for now. These changes do not merge back to /branches/1.7/en because svn.serverconfig.httpd.ref hasn't been backported there (yet?).

Follow up to [r5070]. (Found erroneous change).

(svn.serverconfig.httpd.authz.perdir,
svn.serverconfig.httpd.ref.mod_authz_svn,
svn.serverconfig.pathbasedauthz.getting-started):
Issue [260]. Add info about new `AuthzSVNReposRelativeAccessFile` directive
available in SVN 1.7 and newer.
