`setup/private/path-utils'.
The API is a little different: instead of getting the alist and the
path, there's a curried function that gets the alist and produces a
function to do the substitutions.
`setup/path-relativize'.
`setup/path-relativize' is freed from a bunch of things that were due to
historical baggage, but some remain. (Also, update its docs.)
* Lists are now either blocks or splices depending on whether they
appear inside a block or a splice (default to block).
* Adjusted the docs and a single test where this mattered.
* Change the documentation to be "text.html" and to be titled "text
generation".
I originally picked "under" as the preposition to go before
a platform name, but obviously you should build "on" a
platform, and "under" suddenly annoys me. The choice of "on"
is now codified in the documentation style guide. Meanwhile,
"Unix" insted of "X" seems more clear and consistent in the
`racket/gui' docs.
More usefully, this patch also fixes a few out-of-date
platform-specific claims.
Revert "Fix interface."
Revert "Add more scribble forms that evaluate code and display the results."

by default; a new optional argument restores the old behavior
(but the default behavior is consistent with the old docs and with
the vast majority of existing uses)
The implementation is ugly for performance reasons. A new primitive
`prop:arity-incomplete' property determines when to return #f for
`procedure-arity-includes?' in default mode. A nicer implementation
would be to redefine `procedure-arity-includes?' at the kw-proc level,
but the bytecode optimizer's and JIT's treatment of the built-in
`procedure-arity-includes?' is important. The implementation choice
could be revisited after cross-module inlining is implemented.
Closes PR 11978
The new version fixes some problems with the previous one, most notably
it can create a keyworded function when the last input is is keyworded.
`compose1' is a restricted variant that requires single values in the
composed pipeline -- besides being potentially faster (probably more
if/when there is cross module inlining), it has a semantical
justification, similar to the restricting function call arguments to
return single values, with similar robustness benefits. The
implementation of both is done in a generalized way, and the results can
be faster for both `compose' and `compose1'. (Not by much -- 20% and
30% resp.)
One thing that it could do is to reduce the resulting arity to match the
last given function. I didn't do this since it adds a significant
overhead to the result. (No strong opinion on doing that...)
