# Description
Adds an `extern` definition (`KnownExternal`) for the `nu` command. This
way you can do `help nu` and get tab completions for flags on the `nu`
executable
# User-Facing Changes
* You can now view the flags for Nushell itself with `help nu`, and tab
completion for flags on `nu` works
# Description
Restores `bytes starts-with` so that it is able to work with byte
streams once again. For parity/consistency, this PR also adds byte
stream support to `bytes ends-with`.
# User-Facing Changes
- `bytes ends-with` now supports byte streams.
# Tests + Formatting
Re-enabled tests for `bytes starts-with` and added tests for `bytes
ends-with`.
