Commit Message

[[FIX]] Support semicolons within arrow fn params (#3003)

When JSHint encounters an "open parenthesis" token, it must determine if
the token marks the beginning of an arrow function or a grouping
operator before parsing can proceed.

To make this determination, it inspects the token stream to find the
corresponding "close parenthesis" character.

Previously, this lookahead behavior halted whenever a semicolon token
was encountered. This was presumably an optimization to allow the
algorithm to exit early in the event of an unmatched "open parenthesis"
token.

Because a semicolon token may appear in the parameter list of an arrow
function (e.g. within a default parameter value that is a function
expression), the presence of such a token does *not* necessarily
indicate that the "open parenthesis" is unmatched.

Remove the condition concerning the semicolon character from the
lookahead algorithm.
