Make split_inclusive() on an empty slice yield an empty output `[].split_inclusive()` currently yields a single, empty slice. That's different from `"".split_inslusive()`, which yields no output at all. I think that makes the slice version harder to use. The case where I ran into this bug was when writing code for generating a diff between two slices of bytes. I wanted to prefix removed lines with "-" and a added lines with "+". Due to `split_inclusive()`'s current behavior, that means that my code prints just a "-" or "+" for empty files. I suspect most existing callers have similar "bugs" (which would be fixed by this patch). Closes #89716. |
