[PATCH 1/5] completion: zsh: update installation instructions

[Felipe Contreras]

Commit 0e5ed7cca3 wrongly changed the extension of the bash script
to .zsh. The extension doesn't really matter, but it confuses people.

I've changed the text to make it clear that your zsh script goes to
~/.zsh/_git, and the bash script to ~/.git-completion.bash (or wherever
you want).

Also, update the default locations of the system bash-completion.

[PATCH 3/5] completion: remove zsh hack

[Felipe Contreras]

We don't want to override the 'complete()' function in zsh, which can be
used by bashcomp.

[PATCH 4/5] completion: zsh: improve main function selection

[Felipe Contreras]

Sometimes we want to use the function directly (e.g. _git_checkout), for
example when zsh has the option 'complete_aliases', this way, we can do
something like:

  compdef _git gco=git_checkout

[PATCH 5/5] completion: prompt: fix color for Zsh

[Felipe Contreras]

We don't need PROMPT_COMMAND in Zsh; we are already using %F{color} %f,
which in turn use %{ and %}, which are the equivalent of Bash's
\[ and \].

We can use as many colors as we want and output directly into PS1
(or RPS1) without the risk of buffer wrapping issues.
