##### SUMMARY
If a module sets `add_file_common_args=True` when calling `AnsibleModule`, all elements from [FILE_COMMON_ARGUMENTS](https://github.com/ansible/ansible/blob/e9d29b1fe4285d90d7a4506b80260a9e24c3bcea/lib/ansible/module_utils/basic.py#L229-L257) are included in the argument spec. The [files document fragment](https://github.com/ansible/ansible/blob/e9d29b1fe4285d90d7a4506b80260a9e24c3bcea/lib/ansible/plugins/doc_fragments/files.py#L15-L80) only documents a subset of them, though. Missing are:
 - src
 - follow
 - force
 - content
 - backup
 - remote_src
 - regexp
 - delimiter
 - directory_mode

Most module authors using `add_file_common_args=True` are probably not aware that their modules have these options as well.

I don't think these extra options should be added by default if `add_file_common_args=True` is specified.

short_description: Copy files to remote locations
description:
    - The C(copy) module copies a file from the local or remote machine to a location on the remote machine.
    - Use the M(fetch) module to copy files from remote locations to the local box.
    - If you need variable interpolation in copied files, use the M(template) module. Using a variable in the C(content)
      field will result in unpredictable output.
    - For Windows targets, use the M(win_copy) module instead.
options:
  src:
    description:
    - Local path to a file to copy to the remote server.
    - This can be absolute or relative.
    - If path is a directory, it is copied recursively. In this case, if path ends
      with "/", only inside contents of that directory are copied to destination.
      Otherwise, if it does not end with "/", the directory itself with all contents
      is copied. This behavior is similar to the C(rsync) command line tool.
    type: path
  content:
    description:
    - When used instead of C(src), sets the contents of a file directly to the specified value.
