+Subject: [PATCH] Make completion file compatible with newer bash-completion
+
+Function _have was renamed as _comp_have_command in bash-completion
+commit 6381fd1f ("refactor: `_have => _comp_have_command`") in 2022.
+Since it's relatively recent, let's provide a wrapper to handle the
+API change.
+
+This fixes error message like "bash: have: command not found" when
+completing img2sixel command with bash-completion 2.16.0.
