That presumably means that read-number never worked as originally
expected. The comment in source file says that read-number should be
used for "n" interactive spec, but "n" spec works as expected, so
read-number is not used there.

Wouldn't it be more natural for string-to-number to return nil rather
than 0 in a non-number case?
