bug#21957: 24.5; Make occur search within regions when there is one

[Li Ian-Xue]

Yes, that is what I did when I found out `occur' doesn't do regions. A
friend of mine suggested
that a combination of narrowing (C-x n w) and M-s o should do the trick,
and it did.

Nevertheless still I would still prefer `occur' to accept a regional
parameter,
as it would be much straight forward mode of operation.

Thank you.
