[PATCH v2 00/26] completion: bash: a bunch of fixes, cleanups, and reorganization

I found a couple of bugs and inconsistencies.

Also low-hanging fruit in terms of redundant code that can be merged and removed.

Tons of cleanups.

And refactoring the ancient _get_comp_words_by_ref.

Since v1:

 * Added bug fixes
 * A lot more reorganization
