>Is "their" the usual shorthand for "his or her"? I've read recently that this practice of using the plural as the gender neutral pronoun is a time-honored... workaround for the total lack of reflexive pronouns in English. It was in use in XVI century literature, and though it sounds quite out of whack when you try to translate into any other language, I respect it as such.

Hmmm... I can't tell if you're joking. You do realize that Terry meant "there is", don't you? His spelling and grammar should never be taken too literally.

It's a common grammatical error to use "their" instead of "his" or "her", regardless of the gender obfuscation issue. Who the hell designed this language, anyway? Even those of us who think we know English occasionally stumble into an "its" / "it's" confusion, and I'm amazed at the number of literate people who don't seem to know the difference between loose and lose!
