Description of problem:
dnf module --help refers to module_spec while man page uses module-spec.
With this difference it is a bit more difficult to find what module_spec means.
dnf module --help should refer to module-spec, such as dnf man page.
I create a pull request https://github.com/rpm-software-management/dnf/pull/1327. It replace module_spec by module-spec in help (--help). What about testing? Is it a minor change? If it brakes something other modular tests will catch it.
