Re: master 268e055e051: Limit VC-Dir status process output processing

Hi Sean,

Do you think we could change this improvement in a way that doesn't make 
the 'dir-status-files' backend actions coupled to VC-Dir?

Some sort of setup that VC-Dir would do to its process buffer could lead 
to a more subtle approach.

The way it's implemented here any third-party caller of dir-status-files 
(diff-hl-dired might be the main one) now has to learn of the unrelated 
variable from vc-dir.el.
