Subject: bug#48765: `member` from (scheme base) returns empty list instead of #f when item is not found

Default `member` works fine:

$ guile
> (member 'a '(b))
$1 = #f

However, using scheme base it returns empty list

$ guile --r7rs
> (import (scheme base))
> (member 'a '(b))
$1 = ()

Other functions (memq, memv) seem to work fine.
