--- 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.
