DfRefactor

Leon reports that you also have to take comments into account:

The above problem also exists in comment lines.
Like this, these lines:

// record to the end of the table. In both cases we take
// all record in between, and also add the stepsize

become:

// record to the end of the (both contains table.) cases we take
// all (between, contains record) and also add the stepsize

The "In to Contains" refactoring was done via regular expressions.

While the idea is great, neither of us wanted to support that and as such we pulled the refactoring option and decided that it has to be written using code we can understand and follow without it ending up becoming a puzzle.
