I suppose you mean that `find-file-hidden' should always behave the same
as `find-file-noselect' but for setting the hidden flag.  Just that that
means that hidden buffers will have some not-so-hidden impact.  BTW it
might probably make sense to use a hash table to find hidden buffers
from their visited file names instead of relying on `get-file-buffer'.
