As of new OPAM (OCaml package manager) v2.1, `opam config var share` is no longer supported. Instead, the syntax is `opam var share`. To allow both, this checks first with the new syntax, then if that doesn't work, the old is tried. If neither produce any output, it fails as normal. edit: Fix formatting.
