Add options to match start or end of input

[sindresorhus]

Why? What's your use-case?

I use this regex in a call to Codemirror's stream.match API (https://codemirror.net/doc/manual.html#modeapi) It requires that the pattern has starting anchor ^ so that it can match a token at the beginning of the stream.

Sorry about the delay. Alright. Will merge if you add a couple of tests ;)

Ping @akonsu :)

Closing for lack of response.

Another way is to just wrap it:

const regex = new RegExp(`^${emailRegex().source}`);

regex.match('unicorn hello@example.com');
//=> false

regex.match('hello@example.com');
//=> true
