The range of values used to represent "improper lists"
of length 36 to 65 overlapped with the range of values
used to represent other things.
This bug is the new chapion of the "how did we not hit that
earlier?" category. The bug was introduced around v300, at
the latest.

Using the installation name name seems right, but it creates sandbox
trouble, since finding the instalation name requires several
path-chasing steps. I think the sandbox problem shoudl be fixed,
somehow, but since I don't have a good idea right now, I'm reverting
the PLaneT change.
The intent of disallowing `handle-evt?' arguments to `wrap-evt',
`handle-evt', and `chaperone-evt' was that those extra wrappers
break the tail-handling behavior that is almost certainly intended
when `handle-evt' is used. The extra checking was not obviously
worthwhile (we don't have any checked "this procedure should be called
in tail position" annotations, after all), and pushing the distinction
through Typed Racket looked particularly inconvenient.
Dropping the constraint is trivial if we say that wrapping a
`handle-evt' result disables the tail invocation of the handler
procedure.
When you `raco pkg install' a package that is already present as
an auto-installed package, the installation is promoted to
an explicitly installed package.
When you `raco pkg remove --demote' a package, then it is changed
from an explicitly installed package to an auto-installed package.
Combine `--demote' with `--auto' to remove a package only
if there are no dependencies, leaving it auto-installed otherwise.
The defaults (promote in the case of `install', not demote in the case
of `remove') are different because it seems more likely that you
really mean to remove a package when using `pkg remove', while it
seems likely that you just want to start using a package that happened
to be auto-installed already for `pkg install'.
Also, make the package scope inferred for `raco pkg' commands
that take a list of package names, and fix up lock handling and
error reporting.
* The first change is probably due to a difference in my $LANG, so it
might be better to set it to a known value for testing.
* The second change in an explanation about a corner case in the
installer that would be nice to fix, if it's still done in a similar
way.
In particular, using a shut down eventspace actually returns
the exn:fail exception instead of exn:misc, which does not
exist. Example:
#(struct:exn:fail start in timer%: current eventspace is shutdown:
#<eventspace> #<continuation-mark-set>)
Although not documented as such, the implementation used to return
form did not take the special meaning of #f into account. It seems
better to fix `syntax-local-lift-context' to match its documentation.
Use the `pkg-authors' and `pkg-desc' fields from "info.rkt"
when creating a catalog.
Also add an `archive-catalog' makefile target for assembling
archives (binary for native-library package, source others)
and a catalog in "build/archive".
