[PATCH v1] convert: add test to demonstrate clean invocations

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

If three files processed by a filter are added and committed to a
repository then I expect three clean invocations per Git operation.
Apparently Git invokes the clean process 12 times.

It's pretty late here and I hope do not miss something obvious... but
can anyone explain to me why the clean operation is executed 12 times
for 3 files?

Thanks,
Lars
