  "Define type TYPE.
DOC is a general description and shows up in all docstrings.
It is followed by a list of keywords and functions:

:expand FUNC     Expansion function. This function should accept
                 two positions in the current buffer, BEG and END,
                 and return a pair of expanded buffer positions.
:contract FUNC   The opposite of :expand, optional.
:one-to-one BOOL Whether expansion is one-to-one. This means that
                 :expand followed by :contract always returns the
                 original range.
:normalize FUNC  Normalization function, optional. This function should
                 accept two unexpanded positions and adjust them before
                 expansion. May be used to deal with buffer boundaries.
:string FUNC     Description function. This takes two buffer positions
                 and returns a human-readable string, for example,
                 \"2 lines\".

If further keywords and functions are specified, they are assumed to
be transformations on buffer positions, like :expand and :contract.
