Many minor changes:

Add formatting tags around syntax that was missing. Be consistent.
(Had to manually do this for one in v9_4 as surrounding sentences
had changed. And skipped one not in v9_4.)

Remove a few paragraph breaks before "For example:".

(Skipped fix because problem not in v9_4: Fix typo "will will".)

Change description of pid-file to not mislead (since other programs
don't parse named.conf to figure out the PID file :)
(I had to manually edit this as my patch from HEAD didn't apply here
in v9_4.)

Remove some unneeded commas.

Minor grammar fixes.

Clarify edns-udp-size to say "... to control the size of packets received."
Reformatted that paragragh too (in docbook, not rendered version.
(TODO: cross-reference these descriptions.)

Hyphenate "built-in" to be consistent.

Remove space in "100000" (for style). (Some use space, period, comma
for thousands.)

Capitalize TTL in one place.

Say that the -t option is "for named". (Reformat that paragraph in
docbook while here.)

named is in /usr/local/sbin not /usr/local/bin for example.

BIND 8 is deprecated. Don't publicly say we do security-related patches
for BIND 4 or BIND 8.

(Note I have many, many more improvements to do. Trying to catch up on
all my uncommitted fixes some dating back to 2007. I originally
planned to not backport these from HEAD to v9_6, v9_5, and v9_4,
but now I am doing that.)
