Limit size of expression list in FormCalc parserchromium/3517
Limits the number of elements that can be added to the expressions list in the FormCalc parser. This handles cases like long strings of ! repeated, since ! is a valid identifier and identifiers are valid expression, even though it will be no-op. This is another case of something that is valid, but stupid.
