* t/clean-many.sh: New test, try cleaning ~ 130 thousands files. Currently fails on some systems (e.g., NetBSD 5.1). * t/clean-many2.sh: New test, check that our cleaning rules do not hit errors due to an exceeded command line length when there are many files to clean; it does so by faking a very low command line length limit for 'rm' (max 50 arguments). Currently failing.
