miscommunicated variance information.

5c6498b355 Fix for PR 13234. xexpr-core: added more test cases to 
correct-xexpr?.  Inverted the logic and replaced the
continuation-passing style with simpler test-for-error logic.  Also
corrected typo in attribute symbol checker that could otherwise lead
to a contract error.  (taking the cadr of a non-cadrable value)

672910f27b Lots of bad TAB eliminations. 
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.

If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces.  For example, to see
per-line authors, use "git blame -w <file>".  Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".

8033900674 add ad hoc optimization of car' to unsafe-car', etc. 
In `(if (pair? x) E1 E2)', convert `(car x)' in E1 to
`(unsafe-car x)', and similarly for `(cdr x)'. Also,
`(begin (car x) (cdr x))' converts to `(begin (car x)
(unsafe-cdr x))' since `(car x)' implies a `pair?' test
on `x'.

c02797b121 improve the language dialog a little bit: 
- make clicking on the example languages
  select the 'The Racket Language' radio button
- when the clicked example language matches
  the buffer, have a more friendly message

95679bdab5 Switch from except' (from racket/unit') to #:except' in 2htdp/private'. 
This is used by the `function-with-arity' macro, and the use of `except'
looks like something that is better done with a keyword.  I think that
this change should be fine since it's a private function.

5aca765989 racket' -> racket/base' switches in htdp' and 2htdp'. 
All of these look safe.  Also, see comment in `2htdp/batch-io' about the
splitting thing (which should probably be revised with the extensions to
`racket/string').

d49aeecd8a Switch the teachpack wrappers to `racket/base'. 
(I think that the change to `teachpack/htdp/dir' is fine too, looks like
the previous code is dealing with the old restriction of not requiring a
binding that conflicts with the language bindings.)
