including adding some uses of `with-module-read-parameterization'
so that `read-accept-lang' is set right anyway; still, so many
many places just set `read-accept-reader' to #t that making
`read-accept-lang' #f by default looks like too big of an
incompatibility
which solves the problem of forgetting a Planet-based tool when a
new Planet-based tool is installed (if the old tool used "info.ss"
instead of "info.rkt")
--- a reversal of opinion from my earlier commit; the problem
with syntactic simplification is that it may not refer to the
same file, due to soft links; given that true normalization is
impossible, simplify-path and simple-form-path provide a good
compromise between preserving paths as given and exanding
soft links as neede
A mixture of filesystem-insensitive `simplify-path', filesystem-sensitive
`simplify-path', and `normalize-path' was used in different parts
of `raco setup'. This causes a mismatch, for example, when a Planet
hard link uses a path that is a symlink.
In general, I think filesystem-insensitive simplification (i.e., syntactic
simplification) is the right choice for comparing paths, so that is now
used consistently.
