The reason that this was done is for the sake of shell scripts: They need to
have the path that was finally decided as exec-path in $PATH.
But I can't think of any negative side effect if *all* exec-path candidates
are in $PATH. It's important, though, that all paths are absolute because
the tools chdir every now and then.
