Describe special values in more GUC descriptions.

Browse Source 
Commit 977d865c36 established some rules for mentioning special
values (e.g., -1, 0, an empty string) in GUC descriptions.  A few
parameters either neglect to mention their special values or
describe them in a way that doesn't follow those rules.  Most of
these parameters were added after the aforementioned commit.  This
commit fixes them.
