Bug#931958: package argument silently ignored if -f is present

[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

Package: reportbug
Version: 7.5.2

$ reportbug --template -f /usr/share/bash-completion/completions/umount mount
Finding package for '/usr/share/bash-completion/completions/umount'...   ^
Please re-run reportbug selecting one of these packages:                 ^
  bash-completion                                                        ^
  mount                                                                  ^
                                                                         ^
But I did. It's right there ---------------------------------------------^

There is no error message, thus I am using the program correctly.
It is just silently throwing away the packagename argument.

And in this case there is no way for the user to successfully use the
program non-interactively. (dlocate is installed.)

P.S.,

       -f FILENAME, --filename=FILENAME Report a bug in the package
              containing FILENAME so you don't have to figure out what
              package the file belongs to...

should mention that it also adds a File: header to the report.

(OK, one can use
-f /usr/share/bash-completion/completions/umount$

But then the $ ends up on the File: line. BUG.)
