Create a table of every escaped character and "why"

[domenic]

I've asked for this a couple times, but I think it's crucial to forward progress, especially as people debate additions to the current spec.

Here is a start:

char	reason
^	new RegExp("^") => syntax error; new RegExp("^") => matches the string "^"

Will do

@domenic done :)

Yay! Might want to give it a proofread, but overall very helpful.

If I can weigh in, I think we've nailed the exact list over at https://github.com/sindresorhus/escape-string-regexp/blob/master/index.js#L3

Nevermind, the two seem to already be a 1 on 1 match - so kudos to @benjamingr ;)

The entry for ? should mention the usage of the syntax character in groups, not only as a quantifier.

The WhiteSpace entry in the extended safe set is currently a copy of the / entry. It should rather link to #30, or at least use \n instead of /.

The escaping of hex characters in the beginning should be added as a table entry to "Safe with extra escape set", so that they don't extend decimal or unicode escape sequences (#29).

@bergus can you open a separate issue please? (Pull request would also be welcome)

Agreed with @bergus.

I'd also like to see the "safe with extra escape set" section reference @bergus' rationale for this set.
