Attached is a little patch that cleans up the LaTex output from KFormula.

For example, the integral of x^2 was represented as:

{ \int{{ {}{ x}^{ 2}}}}

Now, it is the following:

\int x^{2}

Is there any active maintainer of KFormula?  I have a few usability
ideas for it, and I would like to know what the maintainer thought of
them.
