That's not "dired support" in any shape or form! That's an emacs kludge
external to dired that exploits how dired handles buffer names (likewise
for grep). Dired internally (in the very line being modified by my
patch) actively subverts having several buffers visiting the same
directory, and my experience in testing is that no harm is done when
using the patch.
