SZEDER Gábor 61d48c66ea completion: correct zsh detection when run from git-completion.zsh
v2.18.0-rc0~90^2 (completion: reduce overhead of clearing cached
--options, 2018-04-18) worked around a bug in bash's "set" builtin on
MacOS by using compgen instead.  It was careful to avoid breaking zsh
by guarding this workaround with

	if [[ -n ${ZSH_VERSION-}} ]]

Alas, this interacts poorly with git-completion.zsh's bash emulation:

	ZSH_VERSION='' . "$script"

Correct it by instead using a new GIT_SOURCING_ZSH_COMPLETION shell
variable to detect whether git-completion.bash is being sourced from
git-completion.zsh.  This way, the zsh variant is used both when run
from zsh directly and when run via git-completion.zsh.

Reproduction recipe:

 1. cd git/contrib/completion && cp git-completion.zsh _git
 2. Put the following in a new ~/.zshrc file:

 	autoload -U compinit; compinit
	autoload -U bashcompinit; bashcompinit
	fpath=(~/src/git/contrib/completion $fpath)

 3. Open zsh and "git <TAB>".

With this patch:
Triggers nice git-completion.bash based tab completion

Without:
 contrib/completion/git-completion.bash:354: read-only variable: QISUFFIX
 zsh:12: command not found: ___main
 zsh:15: _default: function definition file not found
 _dispatch:70: bad math expression: operand expected at `/usr/bin/g...'

Contributed Software

Although these pieces are available as part of the official git
source tree, they are in somewhat different status.  The
intention is to keep interesting tools around git here, maybe
even experimental ones, to give users an easier access to them,
and to give tools wider exposure, so that they can be improved
faster.

I am not expecting to touch these myself that much.  As far as
my day-to-day operation is concerned, these subdirectories are
owned by their respective primary authors.  I am willing to help
if users of these components and the contrib/ subtree "owners"
have technical/design issues to resolve, but the initiative to
fix and/or enhance things _must_ be on the side of the subtree
owners.  IOW, I won't be actively looking for bugs and rooms for
enhancements in them as the git maintainer -- I may only do so
just as one of the users when I want to scratch my own itch.  If
you have patches to things in contrib/ area, the patch should be
first sent to the primary author, and then the primary author
should ack and forward it to me (git pull request is nicer).
This is the same way as how I have been treating gitk, and to a
lesser degree various foreign SCM interfaces, so you know the
drill.

I expect that things that start their life in the contrib/ area
to graduate out of contrib/ once they mature, either by becoming
projects on their own, or moving to the toplevel directory.  On
the other hand, I expect I'll be proposing removal of disused
and inactive ones from time to time.

If you have new things to add to this area, please first propose
it on the git mailing list, and after a list discussion proves
there are some general interests (it does not have to be a
list-wide consensus for a tool targeted to a relatively narrow
audience -- for example I do not work with projects whose
upstream is svn, so I have no use for git-svn myself, but it is
of general interest for people who need to interoperate with SVN
repositories in a way git-svn works better than git-svnimport),
submit a patch to create a subdirectory of contrib/ and put your
stuff there.
