Details:

When layering a store over a file that doesn't exist `storeio' lookup of the
store will return ENOENT, causing clients to use underlying translator
instead.

#v+
$ ls -a
. ..
$ settrans -ac foo -T file bar
$ echo test > foo
$ settrans -g foo
$ cat foo
test
#v-

The solution is to return another error instead.  I'm not sure which one is
appropriate, but I have attached a patch that returns
EGRATUITOUS instead.
