24561e25e4 Finished matrix documentation, attendant fixes; please merge to 5.3.2 
* Narrowed type of `submatrix' to only sensible argument types

* `matrix-invertible?' now returns #f when given a non-square matrix
  instead of raising an error

* Allowed `matrix-diagonal' to operate on non-square matrices

f40ad2ca9d `math/matrix' fixes; please merge to 5.3.2. 
* Fixed type of `matrix-expt'

* Made matrix functions respect `array-strictness' parameter (mostly
  wrapping functions with `parameterize' and return values with
  `array-default-strictness'; reindentation makes changes look larger)

* Added strictness tests

7ab7d97f01 Move cfg-parser from the algol60 collection to parser-tools. 
Discussed in: http://lists.racket-lang.org/dev/archive/2013-January/011416.html

A stub library in algol60/cfg-parser will re-export the contents of
parser-tools/algol60 for backwards compatibility.

986e695bd5 Made arrays strict by default; please merge to release 
* Added parameter `array-strictness', default #t

* Added `array-default-strict!' and `array-default-strict', which act
  like the functions without "default" in the name when
  `array-strictness' is #t; otherwise they do nothing

* Lots of small changes to existing array functions, mostly to ensure
  computations are done using nonstrict arrays, but return values are
  strict when `array-strictness' is #t

* Added strictness tests

* Added tests to ensure untyped code can use `math/array'

* Rewrote `array-map' exported to untyped code using untyped Racket

* Rearranged a lot of `math/array' documentation

131af9955d fix bug introduced in f315f08dc3 
closes PR 13435

Also cleaned up one more threading problem (this one was
probably innocuous, but it is hard to be sure and the
rewrite is easier to see that it isn't problematic)

type variable scoping was fixed.

c8a1ec8c9c fix bug in online check syntax's save file notification 
Before this commit, the files that are loaded during expansion
were discarded when an error during expansion occurs. This commit
saves them: unless the program is something like

  (begin-for-syntax (kill-thread (current-thread)))

the handling that deals with that kind of situation (as opposed
to just an exception being raised) doesn't try to save them

Do not merge to 5.3.2: this bug isn't serious and the new code
is not as well tested as the old

860cc3cbed Added quote-srcloc-string and quote-srcloc-prefix to syntax/location. 
Also cleaned up implementation; only generates syntax for requested part(s) of
source location, and is more intelligent about calculation of relative paths.
