Description

For aliases, the bash completion is broken. It only completes one element and it's always completed to the first argument in the alias.

Steps to Reproduce the Problem

1. Create an alias gp = ["git", "push"]
2. source <(COMPLETE=bash jj)
3. Type jj gp and then hit <Tab>

Expected Behavior

Completion behaves the same as if I had typed jj git push, i.e. it would add -- to my prompt.

Actual Behavior

The completion adds push to my prompt. It even replaces partial input with push, i.e. jj gp --he + <Tab> becomes jj gp push.
