* ake string_util::WriteInto() DCHECK() that the supplied |length_with_null| > ↵pkasting@chromium.org2011-11-291-2/+2
| | | | | | | | | | | | 1, meaning that the without-'\0' string is non-empty. This replaces the conditional code added recently that makes this case return NULL. It's easier to understand if it's simply an error to call WriteInto() in this case at all. Add DCHECK()s or conditionals as appropriate to callers in order to ensure this assertion holds.

| | | | | | | | | | | test that would have caught bug. Also add a test to verify that our random generators are at least somewhat random.
