Summary: expr {"Nan"}

Initial Comment:
The expr command, when given the literal string "Nan"
(quotes included), tries to convert Nan to a number and
 yields the error:

     domain error: argument not in valid range

Clearly, what's inside quotes is not expr's business,
it shouldn't open that box !

Also notice that this strange behavior is insensitive
to whitespace, but it to other characters:

   expr {"Nan xyz"}

works correctly.
