RVM 1.25.29 breaks git tab completion

_README

See https://github.com/wayneeseguin/rvm/issues/3076

My envioronment:

* OSX with homebrew
* ZSH 5.0.6 (installed via homebrew)
* git 2.1.1 (installed via homebrew)
* RVM 1.25.33 (installed via curl from rvm.io)
* fpath automatically set to: /usr/local/share/zsh/site-functions /usr/local/Cellar/zsh/5.0.6/share/zsh/functions
* Files:
  * ~/.zshrc (see zshrc below)
  * /usr/local/share/zsh/site-functions/_git (symlink to homebrew's git 2.1.1 site-functions, see git_git below)
  * /usr/local/share/zsh/site-functions/git-completion.bash (symlink to homebrew's git 2.1.1 git-completion.bash, see git-completion.bash)
  * /usr/local/Cellar/zsh/5.0.6/share/zsh/functions/_git (see zsh_git below)
  * ~/.zcompdump is auto-generated, remove it before trying to reproduce
  
There may be other files contributing to this, there are over 928 default function files in /usr/local/Cellar/zsh/5.0.6/share/zsh/functions

# bash/zsh completion support for core Git.
#
# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
# Distributed under the GNU General Public License, version 2.0.
#
# The contained completion routines provide support for completing:
#
#    *) local and remote branch names
#    *) local and remote tag names
#    *) .git/remotes file names
#    *) git 'subcommands'
#    *) tree paths within 'ref:path/to/file' expressions
#    *) file paths within current working directory and index
#    *) common --long-options
#
# To use these routines:
#
#    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
#    2) Add the following line to your .bashrc/.zshrc:
#        source ~/.git-completion.sh
#    3) Consider changing your PS1 to also show the current branch,
#       see git-prompt.sh for details.
#
# If you use complex aliases of form '!f() { ... }; f', you can use the null
# command ':' as the first command in the function body to declare the desired
# completion style.  For example '!f() { : git commit ; ... }; f' will
# tell the completion to use commit completion.  This also works with aliases
# of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".

# This function can be used to access a tokenized list of words
# on the command line:
#
#	__git_reassemble_comp_words_by_ref '=:'
#	if test "${words_[cword_-1]}" = -w
#	then
#		...
#	fi
#
# The argument should be a collection of characters from the list of
# word completion separators (COMP_WORDBREAKS) to treat as ordinary
# characters.
#
# This is roughly equivalent to going back in time and setting
# COMP_WORDBREAKS to exclude those characters.  The intent is to
# make option types like --date=<type> and <rev>:<path> easy to
# recognize by treating each shell word as a single token.
#
# It is best not to set COMP_WORDBREAKS directly because the value is
# shared with other completion scripts.  By the time the completion
# function gets called, COMP_WORDS has already been populated so local
# changes to COMP_WORDBREAKS have no effect.
#
# Output: words_, cword_, cur_.

# You need git's bash completion script installed somewhere, by default it
# would be the location bash-completion uses.
#
# If your script is somewhere else, you can configure it on your ~/.zshrc:
#
#  zstyle ':completion:*:*:git:*' script ~/.git-completion.sh
#
# The recommended way to install this script is to copy to '~/.zsh/_git', and
# then add the following to your ~/.zshrc file:
#
#  fpath=(~/.zsh $fpath)

# Some parts of this completion's behaviour are configurable:
#
# Say you got your own git sub-commands (git will run a program `git-foo'
# when you run "git foo") and you want "git f<tab>" to complete that sub
# commands name for you. You can make that sub-command know to the completion
# via the user-command style:
#
#     % zstyle ':completion:*:*:git:*' user-commands foo:'description for foo'
#
# `user-commands' is a list style, so you can add any number of programs there.
# The :description part is optional, so you could add all git-* programs from
# your $path like this:
#
#     % zstyle ':completion:*:*:git:*' user-commands ${${(M)${(k)commands}:#git-*}/git-/}
#
# A better solution is to create a function _git-foo() to handle specific
# completion for that command.  This also allows you to add command-specific
# completion as well.  Place such a function inside an autoloaded #compdef file
# and you should be all set.  You can add a description to such a function by
# adding a line matching
# 
#     #description DESCRIPTION
#
# as the second line in the file.  See
# Completion/Debian/Command/_git-buildpackage in the Zsh sources for an
# example.
#
# As this solution is so much better than the user-commands zstyle method, the
# zstyle method is now DEPRECATED.  It will most likely be removed in the next
# major release of Zsh (5.0).
#
# When _git does not know a given sub-command (say `bar'), it falls back to
# completing file names for all arguments to that sub command. I.e.:
#
#     % git bar <tab>
#
# ...will complete file names. If you do *not* want that fallback to be used,
# use the `use-fallback' style like this:
#
#     % zstyle ':completion:*:*:git*:*' use-fallback false

# TODO: There is still undocumented configurability in here.
