Incidental note: I've never understood how people who use "it's" as a
possessive never even think to use "hi's" (though some use "her's" and
"their's").

Yup, me too. I listen to "A Way With Words," a radio program on KPBS
(available streaming at kpbs.org) whose host is language writer Richard
Lederer ("Anguished English," "Get Thee To A Punnery," etc). Richard said
that "it's" for "its" (possessive) was considered correct until near the end
of the 19th century. I didn't know that.
