lib/pp.rb: remove alias for suppressing a redefinition warning.

2017-12-11T04:46:57+00:00

Because there is now the same guard in prelude.rb (alias pp pp).

lib/pp.rb: no rdoc of alias to suppress a warning

pp.rb: rdoc

2017-12-08T07:17:34+00:00

* lib/pp.rb (pp): move pp alias before its rdoc, not to prevent
  parsing.

Replace Kernel#pp after PP class is defined.

2017-12-01T10:48:29+00:00

Avoid a race condition which a context switch
occur after replacing Kernel#pp but before
defining PP class.

Following patch, inserting sleep, makes
this problem reproducible.

With the above patch, "uninitialized constant Kernel::PP" can
happen as as follows.

```

  Thread.current.report_on_exception = true
  pp :foo1

Add missing :nodoc: comment

2016-12-10T18:23:33+00:00

We were missing a `:nodoc:` magic comment that was making automated tools show
that this method was missing documentation, when it really didn't need to be
documented.
