Hint box with Requirement xrefs could show target block title

[bsmith-n4]

When completions are shown in the hint box, it might be possible to show the requirement title as well as the requirement ID as this is more informative.

This should be quite easy actually, but I'm having trouble with how Sublime is dealing with newlines, for some reason.

The following regex works fine (in all versions of ruby): http://rubular.com/r/co6KPz3J9p

But this does not work at all when trying to exclude titles from matching when they are on a line previous to definitions, e.g.;

  block_title:
    comment: |
      Title of a block. Exludes custom block titles for better
      scoping / preventing overlap.

      Examples:
        .My title
        Lorem ipsum dolor.
    name: markup.heading.block.asciidoc
    match: (\..+?\n)(?!\[(def|req))
    captures:
      '1': {name: markup.underline.begin.asciidoc}

note: as stated in the Sublime Text Docs the Oniguruma (Ruby) syntax is used in this case.

OK... so matching more than one line at a time using regular expressions is actually not possible;
see 12.2 Language Rules.

I'll investigate if this is possible through some other means.
