Cull extraneous whitespace.

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.
