What would a Java regex tidier do?

Here are some ideas:

1. remove nugatory \ quoting

2. convert \s*\s* --> \s*

3. alphabetise | lists.

4. remove (?:... ) that is not doing anything.

5. put [..] lists in canonical order.  

6. Convert runs of 4+ to a-d notation.

7. use negative char lists when it would shorten the list.
