tdf#128538: Open filesystem directories in Finder after all

Where option "-R" means, according to the open(1) man page: "Reveals the file(s)
in the Finder instead of opening them."  This appears to always reveal in
Finder, even for *.app "application directories", so should not affect
CVE-2019-9847.)
