regex deconstructor

[Brian Milby]

I did take a look at Atom and is also has some duplicates in the
increase/decrease sections.  It seems to work to out dent the line.  For
example, if you type “switch” the next line will start indented one level.
When you type “case” it moves that line out and the next one is indented.
This actually works fine in normal use.  In the middle of the case block
you are already indented.  Starting a new case will push that line out.
The down side is that you have to manually indent the first case after it
gets pushed out.
