Get pod/perldelta in shape.
* Fixed POD issues.
* Fixed spelling.
* Removed most of the templating stuff; only the Module List and
Acknowledgment are left -- they will be done at the day of the release.

-XXX Remove this section if not applicable.
+A crafted regular expression could cause heap-buffer-overflow write during
+compilation, potentially allowing arbitrary code execution.
-The following modules will be removed from the core distribution in a
-future release, and will at that time need to be installed from CPAN.
-Distributions on CPAN which require these modules will need to list them as
-prerequisites.
+L<[perl #133423]|https://rt.perl.org/Ticket/Display.html?id=133423>
-The core versions of these modules will now issue C<"deprecated">-category
-warnings to alert you to this fact. To silence these deprecation warnings,
-install the modules in question from CPAN.
-
-Note that these are (with rare exceptions) fine modules that you are encouraged
-to continue to use. Their disinclusion from core primarily hinges on their
-necessity to bootstrapping a fully functional, CPAN-capable Perl installation,
-not usually on concerns over their design.
