Closing the REPL with Ctrl+D does not issue a newline, so the user's
prompt displays on the same line as the `scala>` prompt. This is bad.
We now force a newline before closing the interpreter, and display
`:quit` while we're at it so that people know how to exit the REPL
(since `exit` doesn't exist anymore).
The tricky part was to only add a newline when the console is
interrupted, and *not* when it is closed by a command (like `:quit`),
since commands are processed after their text (including newline) has
been sent to the console.

It’s almost 1am, so I’m only scratching the surface, mechanistically
applying the renames that I’ve written down in my notebook:
* typeSignature => info
* declarations => decls
* nme/tpnme => termNames/typeNames
* paramss => paramLists
* allOverriddenSymbols => overrides
Some explanation is in order so that I don’t get crucified :)
1) No information loss happens when abbreviating `typeSignature` and `declarations`.
We already have contractions in a number of our public APIs (e.g. `typeParams`),
and I think it’s fine to shorten words as long as people can understand
the shortened versions without a background in scalac.
2) I agree with Simon that `nme` and `tpnme` are cryptic. I think it would
be thoughtful of us to provide newcomers with better names. To offset
the increase in mouthfulness, I’ve moved `MethodSymbol.isConstructor`
to `Symbol.isConstructor`, which covers the most popular use case for nme’s.
3) I also agree that putting `paramss` is a lot to ask of our users.
The double-“s” convention is very neat, but let’s admit that it’s just
weird for the newcomers. I think `paramLists` is a good compromise here.
4) `allOverriddenSymbols` is my personal complaint. I think it’s a mouthful
and a shorter name would be a much better fit for the public API.

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.

When -feature has not been enabled, we were double counting
identical feature warnings that were emitted at the same position.
Normal error reporting only reports the first time a warning
appears at a position; feature warning counter incrementing
should behave the same way.
@hubertp: Fixed .check files that were broken in the original commit.

This brings all the files into line with the .gitattributes
settings, which should henceforth be automatically maintained
by git.

Some of the symbols inside the compiler get created on the fly,
because there are no physical entities in classfiles corresponding to them.
This curious fact needs to be taken into account when loading symbols,
so that the magic symbols get correctly loaded by reflective mirrors.
magicSymbols (as defined in Definitions.scala) include not only
top-level classes, but some other stuff (e.g. String_+ or methods on Any).
Hence a filtering was done to exclude the stuff that's irrelevant
to reflective symbol loading.
Unfortunately a filter was configured to accept only _.isClass,
which consequently ruled out scala.AnyRef (that is a type alias).
