[OS X TeX] American Foot & Inch Symbols

[David Watson]

The credit is due to Donald Knuth, cf. page 130 of The TeXbook,  
Chapter 16 "Typing Math Formulas."

The single right apostrophe -> ' <- should do the same in math mode as  
$^{\prime}$.

I would advise anyone who is interested in TeX to acquire the TeXbook,  
simply to have the definitive resource on hand.
