opam show -f version: ./opam does not read the given opam file.

[dbuenzli]

It seems to consult the opam-repository, e.g. here in the repo of uucp (whose opam file has no version: field).

> opam show --normalise -f version: ./opam
"11.0.0"

Here in an opam file which has no version field and which opam doesn't seem to match to an existing package:

> opam show --no-lint --normalise -f version: ./opam
"~dev"

In fact, the actual checkout order is from: pinned, installed, repo. For an unknown package, it will behave as a pin: if no version given, it is a ~dev package.
But yes, if an opam file is given, it should give that file version, not the pinned/installed one.
