Version Control With Subversion Source

Indexing work. Most of this is syntactic: the way we were doing index
tagging left gaping whitespace holes in the PDF versions of the book.
Some is semantic, trying to ensure that anywhere we have a <firstterm>
tag, we also have an index reference, etc.

Add Emacs mode hint line.

Fix some fat-fingered tag IDs.

For issue 178 ("document ephemeral txnprops (new in 1.8) and how hook
scripts might use them."), document the ephemeral transaction
properties in the property reference section. We still need to give
examples of their utility.

* en/book/ch03-advanced-topics.xml
(svn.advanced.props.ref.ephemeral): New section.

Finish issue 176 ("'start-commit' hook script changed in Subversion
1.8.").

* en/book/ch04-branching-and-merging.xml
(svn.branchmerge.advanced.hook-ex1): Update start-commit hook
example.

* en/book/ref-reposhooks.xml
(svn.ref.reposhooks.start-commit): Update start-commit hook
reference material.

Fix issue 169 ("In Subversion 1.8, the --accept option to 'svn
resolve' is optional.").

* en/book/ch02-basic-usage.xml,
* en/book/ref-svn.xml
Rework bits of text to no longer imply that 'svn resolve' requires
the --accept option.
