So I was actually going for easier to copy/paste here, but perhaps in other environments it's not easier?

Some new feedback.  I find this output confusing since there is a colon
before the <>:

	Report bugs to <pgsql-bugs@lists.postgresql.org>.
	PostgreSQL home page: <https://www.postgresql.org/>

Does this look better (no colon)?

	Report bugs to <pgsql-bugs@lists.postgresql.org>.
	PostgreSQL home page <https://www.postgresql.org/>

or this (colon, no <>)?

	Report bugs to <pgsql-bugs@lists.postgresql.org>.
	PostgreSQL home page:  https://www.postgresql.org/

or maybe this?

	Report bugs:  pgsql-bugs@lists.postgresql.org
	PostgreSQL home page:  https://www.postgresql.org/

or this?

	Report bugs <pgsql-bugs@lists.postgresql.org>
	PostgreSQL home page <https://www.postgresql.org/>

I actually have never seen URLs in <>, only email addresses.  I think
using <> for URLs and emails is confusing because they usually have
different actions, unless we want to add mailto:

	Report bugs <mailto:pgsql-bugs@lists.postgresql.org>
	PostgreSQL home page <https://www.postgresql.org/>

or

	Report bugs mailto:pgsql-bugs@lists.postgresql.org
	PostgreSQL home page https://www.postgresql.org/

I kind of prefer the last one since the can both be pasted directly into
a browser.
