elapsedMillis documentation inconsistent

[mborgerson]

in the 'gotchas' column of the timing function table it says:
"Variables must be outside functions. Avoid compare equals."

Yet the timeout waiting for input example has the 'waiting' variable inside loop();

It's definitely okay to define elapsedMillis inside a function. Can only guess that's a very old comment.
