Linking YETUS-946.  There have been two major Checkstyle versions released since the code was originally written. There is a very high probability that a lot of the extra processing is no longer needed.  But someone needs to sit down and run through it.

> The checkstyle output postprocessing is very slow when there are a lot of changed files.
> My run generates a 26MB raw output, while the yetus processed file is 12MB.
> I suspect that the append operation in the following line gets slower as the file gets bigger, but I lack the bash expertise to tell if/how the filtering can be improved:
