rot13 'g??' shortcut depends incorrectly on mapping of '?'

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run vim -u NONE
2. Insert text "test"
3. Press "g??"
4. Text in buffer is now "grfg" as expected.
5. :map ? -
6. Press "g??".

What is the expected output? What do you see instead?
Expected "test".
Saw instead "grfg".

What version of the product are you using? On what operating system?
Vim 7.3.429
Vim 7.4.475 (compiled with default options from 79c59b4c9d20)
Ubuntu 12.04.5 LTS

What you are seeing here as a variant of what is described in the help at:
                                                        g? rot13
  g?{motion}              Rot13 encode {motion} text. {not in Vi}

which in your case translates to Rot13 encode the current line and the line 
above ('-' motion).

Since you do not have a line above, the command aborts. Leaving you with the 
Rot13 encoded word.

Ah, I see. A bit unorthogonal since you cannot then use backward search for the 
motion ;-)

Thanks for the reply!
