Re: [PATCH 1/2] test-lib: allow test snippets as here-docs

We lose `chainlint` functionality for test bodies specified in this manner.

Ouch.

Restoring such functionality will require some (possibly)
not-so-subtle changes. There are at least a couple issues which need
to be addressed:

(1) chainlint.pl:ScriptParser::parse_cmd() only currently recognizes
`test_expect_* [prereq] 'title' 'body'` but will now also need to
recognize `test_expect_success [prereq] 'title' - <body-as-here-doc>`.

(2) Until now, chainlint.pl has never had to concern itself with the
body of a here-doc; it just throws them away. With this new calling
convention, here-doc bodies become relevant and must be returned by
the lexer. This may involve some not-so-minor surgery.
