For example, typing
M-x vc-print-branch-log RET
on the project's *compilation* buffer signals the error:
"Buffer *compilation* is not associated with a file"
I think this restriction should be lifted, so vc commands should
work even when called on non-file buffers whose default-directory
is inside the vc project.

Agreed.
Does this patch help, or does it miss more cases?

Strange, this patch has no effect, the same error remains.

Sorry, that was a brain fart.

Thanks for finding the right place to fix, and it should also fix all
other vc commands that failed on non-file buffers.

It seems this code is not necessary anymore because before this code
gets executed, vc-responsible-backend already signals its error
"No VC backend is responsible for file".
