Unfortunately, 1364-2005 5.2.3.3 indicates that an empty string is equivalent to "\0", and is 8 bits wide, so that's wrong. After this commit, a replication operation with a count of zero is used instead, which is explicitly permitted per 1364-2005 5.1.14, and is defined to have size zero. (Its operand has to have a non-zero size for it to be legal, though.) Fixes #948 (again).
