Re: lpeg as a part of lua (was: An introduction to Lua)

It was thus said that the Great Charles Heywood once stated:

  Reread the pattern:

	%?.-([^$][^$][^$])%$

  So,

	?123$		- matches, should return 123
	?987654321$	- matches, should return 321
	?12$		- no match, should return nil
	?12$$		- no match, shoudl return nil

which means the LPeg pattern I gave is slightly incorrect.  I'll fix it in
another message.
