##### SUMMARY
When I read the `copy` documentation, I couldn't work out what it meant.  Unfortunately, this meant it sounded like it might be a weird sex joke.

It doesn't sound like a big problem, but in an ideal world, I think we should prefer to avoid weird sex jokes in an alias for a parameter called `force`.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
copy

##### ADDITIONAL INFORMATION
Issue search tells me "thirsty" was added as an option to the `get_url` module.  In that context, it is appropriate.  But in the context of the `copy` module, it does not make sense, because `copy` only works in the upload direction.

The first three pages of Google Search results (Ansible thirsty) show people using "thirsty" for downloads only, not uploads.  Similarly for GitHub code search (copy thirsty language:YAML).

    - The permissions of the destination file or directory.
    - For those used to C(/usr/bin/chmod) remember that modes are actually octal numbers.
      You must either add a leading zero so that Ansible's YAML parser knows it is an octal number
      (like C(0644) or C(01777))or quote it (like C('644') or C('1777')) so Ansible receives a string
      and can do its own conversion from string into number. Giving Ansible a number without following
      one of these rules will end up with a decimal number which will have unexpected results.
    - As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, C(u+rwx) or C(u=rw,g=r,o=r)).
    - As of Ansible 2.3, the mode may also be the special string C(preserve).
    - C(preserve) means that the file will be given the same permissions as the source file.

  directory_mode:
    description:
    - When doing a recursive copy set the mode for the directories.
    - If this is not set we will use the system defaults.
    - The mode is only set on directories which are newly created, and will not affect those that already existed.

  remote_src:
    description:
    - Influence whether C(src) needs to be transferred or already is present remotely.
    - If C(no), it will search for C(src) at originating/master machine.
    - If C(yes) it will go to the remote/target machine for the C(src).
    - C(remote_src) supports recursive copying as of version 2.8.
    - C(remote_src) only works with C(mode=preserve) as of version 2.6.
