bug#2675: 23.0.91; unnecessary vc-next-action conflicts in vc-dir directory

[Note: I have Dan's patch for fixing whole-directory vc-dir commit in
Git applied, though I don't think it should affect the following, as it
relates to final commit.]

If I have a vc-dir buffer showing a tree with some "up-to-date" entries
from previously committed files, and also some entries for newly changed
files:

   VC backend : Git
   Working dir: /tmp/zonk/
   Branch     : master

                            ./
        up-to-date          newf2
        up-to-date          newf3
        unregistered        newf4
        up-to-date          ppling

Then hitting "v" on the first line of the buffer gives the following
error:

   vc-dir-deduce-fileset: /tmp/zonk/newf4:unregistered clashes with /tmp/zonk/newf2:up-to-date

This seems like a silly and pointless error -- it should probably simply
ignore any "up-to-date" entries when checking for conflicts.

[I know, I can use the "x" command to flush those up-to-date entries -- 
but I shouldn't have to, and not every user will know about that command
(or know to use it, given the slightly obscure error message).]

Thanks,

-Miles
