                                ^^^^     ^^^^^     ^^^^^

Why can there be a whitespace in front of a delivery-value?  And since
it can be, why not in front of a single pdm as well?  Also, why are the
spaces around '$' mandatory (instead of 'whsp')?

Why does it start with space?  That doesn't seem to accomplish anything.

                      ^^^^^
Again, why the initial space?


('space' = mandatory space(s), 'whsp' = optional space(s).)
