.dir-locals.el settings do not apply to buffers when (null
buffer-file-name) even when `default-directory' for those buffers is
dominated by .dir-locals.el.
VC for example creates buffers for which it would be good to be able to
have .dir-locals.el. Examples: the log-edit-mode buffers - be able to
set some checkin rules, or automatically add things to the commit
message, the vc-diff buffers - show trailing whitespace, etc.

I noticed this limitation as well and know no reason why it should be.
For file-local variables it is justified because only file can hold a list
of file-local variables. But I think dir-local variables should have
a wider coverage including non-file buffers.

The idea sounds good, but I'm not sure how it should be implemented.
Non-file buffers tend to be built in different ways (and their
default-directory may be set at different times, and/or may or may not
matter depending on the buffer), so they probably would need to
explicitly ask for dir-locals to be applied, rather than having it be
applied automatically to all non-file buffers.
Patches/ideas welcome,
Stefan
