85d3daa8c1 Use a different default template when there are no args. 
This eliminates extraneous empty lines when there are no user-defined
args, the default args are disabled, and `after_help` is set.

afcacb0626 Apply wrapping to {author} and {about} template tags. 
Previously wrapping was only applied to the {*-with-newline} variants.

059503e54d Make {before-help} and {after-help} template tags include padding. 
Previously there were separate tags for this, {before-help-padded} and
{after-help-padded}. Those have been removed and the default ones
given their behavior.

a87320ae88 Use a template to produce the default help message. 
This makes some changes to the template system:

- Template tags for optional items (like {author}) now expand to
  nothing when the value is unset instead of a default string (like
  "unknown author").
- Many template tags now emit line-wrapped output to match
  write_default_help.
- Items with long variants now expand to the appropriate thing for -h
  vs --help.
- The now-obsolete {long-about} tag has been removed.
- A few new tags have been added.

These are externally-visible changes, but if this makes it into 3.0
that's probably reasonable?

Note that line-wrapping can have some odd edge cases since it does not
account for preceding/trailing characters on the same line as the tag.
This is already the case in master, but will affect some additional
tags with this changeset. See #2065 for details.

Closes #2002.
