Updates for the Tracking a Development Branch section

Grammar tweaks for correctness and readability.

Add missing punctuation.

Prefer <application>svn</application> to <application>SVN</application>;
the latter occurred in only one place.

Remove a redundant list item about Subversion versus CTM.
