Zbigniew Jędrzejewski-Szmek 435ce146ac basic/strbuf: include empty strings in count
Not that it matters much, but it seems cleaner to also count those
inputs, even if they do not consume extra storage space.

The test is extended to include an empty input and counts in the test are
adjusted to include it.
