Okay, you’re right.  “perltidy” it is, then! :)

I just checked the packaging guidelines in the manual and couldn’t find
any statement on when to use “file-name”.  It is only described in
section 5.1.2:

     ‘file-name’ (default: ‘#f’)
          The file name under which the source code should be saved.
          When this is ‘#f’, a sensible default value will be used in
          most cases.  In case the source is fetched from a URL, the
          file name from the URL will be used.  For version control
          checkouts, it is recommended to provide the file name
          explicitly because the default is not very descriptive.

I think the original name is descriptive enough as it actually contains
the name of the package.

So I think you can remove the “file-name” expression and push this.
