I would like to discuss overall strategy first.  Since I have a fully
working implementation for all supported backends at
https://github.com/wolfmanx/vc-ign that does not interfere with the
current vc commands, it would be helpful, if you could load it and
evaluate the use cases 'z i' and 'z p' in 'vc-dir-mode', 'C-x v z i'
and 'C-x v z p' in 'dired-mode' and in a file buffer, just to see if
we can agree on a direction before discussing details.

I think a good point to start is the elimination of all
backend-specific 'vc-ignore' implementations ('vc-cvs-ignore',
'vc-svn-ignore').  That is one goal which is easily achievable.  The
benefit is a uniform implementation across all backends with
'vc-default-ignore' as the central implementation of algorithms,
without duplication of code in backends.
