I see there are two different issues.  The first is, vc-find-version
doesn't inhibit file-name-handlers when creating backup files, as you
mentioned above.  The second is, if you want to make diffs for decrypted
text, it has to be written into files since ediff calls the external
program to compute diffs.  Which may cause a security problem unless
Emacs warns about it.

Something different.  jka-compr seems to have the same issue on "*.gz"
files.  So... can this kind of problem be better solved by advices (or
hooks, if any) to ediff-revision?
