It would be great if Valgrind xml could be turned into one-test-failure-per-error as an option.

The current support turns the whole valgrind run into one test, which either passes or fails.
This is great if you're starting from a zero-problem situation, however, if you're starting from a 1000s-of-problems situation, it would be great to be able to see the trend graph going down over time.

I believe the proposal I make will address this, and might only need an xslt, but I don't have the xml skills to make that work...
