Docs say 'if' when they meant to say 'of'

[LegalizeAdulthood]

On the page Parsing in Detail the docs say:

Control passes up to the parent if int_pair, +int_pair.

they meant to say

Control passes up to the parent of int_pair, +int_pair.

Thanks for pointing out all these typos! These small mistakes are essentially invisible to me. I'vebeen reading, re-reading, and editing these docs for weeks, and still missed all this stuff. This and the other open issues are fixed on my mid-review branch.
