fix Bash completion on macOS (#2074)

Browse Source 
* fix Bash completion on macOS

The Homebrew-provided bash-completion is version 1.x,
which doesn't provide _init_completion. We add a standard
shim instead.

* Add entry to CHANGELOG

* Update CHANGELOG.md

Co-authored-by: Ville Skyttä <ville.skytta@iki.fi>

* review: avoid calling _split_longopt repeatedly
