It's kind of difficult to decide if something might be a keyword
in VimL because it allows you to abbreviate them. In fact,
'ab[breviate]' is a good example. :ab, :abbre, or :abbreviate are
valid ways to call it so rather than making really awful regexps
like::
\bab(?:b(?:r(?:e(?:v(?:i(?:a(?:t(?:e)?)?)?)?)?)?)?)?\b
we match `\b\w+\b` and then call is_in() on those tokens. See
`scripts/get_vimkw.py` for how the lists are extracted.
