auth-source-file-name-p could scan the auth-sources declarations for a
file based backend, and return t for such files. Shouldn't be too hard
to implement (oops, do I offer to volunteer?)

Let's start with bookmark-inhibit-bookmark-hook, adding
tramp-crypt-file-name-p and epa-file-name-p, and see, who else wants to
be added.

Best regards, Michael.
