[PATCH 00/51] completion: revamp

This patch series revamps the completion code to git-completion 1.4.

I used to send this series minimizing the delta to git upstream in order to maximize the chances of it being merged, but it has not received any feedback since the first time it was sent in 2020 [1], so it is safe to say upstream has zero interest in getting this merged. It makes no sense for me to do extra work to maximize the chances of something that will never happen.

Therefore this series starts with the most intrusive change: zsh completion tests.

For several years git-completion has been running zsh completion tests to make sure everything works correctly, not only for bash, but also for zsh.

The zsh code delta between upstream and git-completion results in 14 tests now passing. The new patch series makes that clear now.

Here's a summary of the differences between upstream and git-completion:

 * Fixed alias regression
 * Make tests work when user has configured GIT_PS1_* variables
 * Enable colors in bash without prompt command
 * Fix suboptions for zsh
 * Fix COMP_WORDBREAKS handling
 * Fix main option handling for zsh
 * Fix -C handling for zsh
 * Fix -c handling for zsh
 * Fix generic completions for zsh
 * Fix configurations with value for zsh (e1e00089da)
 * Fix option relationships for zsh
 * Add improved removable suffix for zsh
 * Plenty of reorganizations and cleanups

Cheers.
