bug#11328: 24.1.50; Comment in `dired-copy-file-recursive' code

[Stefan Monnier <monnier@IRO.UMontreal.CA>]

I really appreciate your nit-picks (I know the word sounds negative,
but to improve code-quality, it's really what is needed).  But please,
please, pretty please, get yourself access to the Bzr so you can fix
those things yourself.
You'll be happier, we'll be happier, the world will smile, birds will
sing.
