It turns out 'words' is a special variable used by zsh completion. This was not isolated correctly in zsh's bash completion emulation, so by trying to set it as 'local' in git's completion, unexpected results occur; assignations are not propagated to outer levels in the call stack. This is now fixed in the latest master branch of zsh[1] by simply defining 'words' as hidden (typeset -h), which removes the special meaning inside the emulated bash function. It probably won't be released until version 4.3.12. In the meantime, we can workaround the issue by doing the same; defining words as hidden (typeset -h) as soon as possible. Right now zsh is completely broken after commit da48616 (bash: get --pretty=m<tab> completion to work with bash v4), which introduced _get_comp_words_by_ref() that comes from bash-completion[2] scripts, and relies on the 'words' variable to behave like any normal variable.
