One last flurry with the broom before I leave you slobs to code
in your own filth. Eliminated all the trailing whitespace I
could manage, with special prejudice reserved for the test cases
which depended on the preservation of trailing whitespace.
Was reminded I cannot figure out how to eliminate the trailing
space on the "scala> " prompt in repl transcripts. At least
reduced the number of such empty prompts by trimming transcript
code on the way in.
Routed ConsoleReporter's "printMessage" through a trailing
whitespace stripping method which might help futureproof
against the future of whitespace diseases. Deleted the up-to-40
lines of trailing whitespace found in various library files.
It seems like only yesterday we performed whitespace surgery
on the whole repo. Clearly it doesn't stick very well. I suggest
it would work better to enforce a few requirements on the way in.

Imported sbt.Process into trunk, in the guise of package
scala.sys.process. It is largely indistinguishable from the version in
sbt, at least from the outside.
Also, I renamed package system to sys. I wanted to do that from the
beginning and the desire has only grown since then. Sometimes a short
identifier is just critical to usability: with a function like error("")
called from hundreds of places, the difference between system.error and
sys.error is too big. sys.error and sys.exit have good vibes (at least
as good as the vibes can be for functions which error and exit.)
Note: this is just the first cut. I need to check this in to finish
fixing partest. I will be going over it with a comb and writing
documentation which will leave you enchanted, as well as removing other
bits which are now redundant or inferior. No review.

Explaining something for the (largeish N)th time finally awoke me to
the fact that software can explain things. I labored a long time over
this error message: I'm sure it can still use work (and/or it will drive
scalaz users off some kind of cliff) but the simple common case people
have so much trouble with is lit up like a christmas tree and for this I
will take some bullets.
build/pack/bin/scala -e 'class Foo[T] ; Set[Foo[AnyRef]]() + new
Foo[String]' :1: error: type mismatch; found : this.Foo[String]
required: this.Foo[java.lang.Object] Note: String <: java.lang.Object,
but class Foo is invariant in type T. You may wish to define T as +T
instead. (SLS 4.5) class Foo[T] ; Set[Foo[AnyRef]]() + new Foo[String]
