Subject: Bug with bash completion emulation
From: Felipe Contreras <felipe.contreras@gmail.com>

Hi,

The following script shows a problem that happens with git's bash completion:

---
#!/bin/sh

if [[ -n ${ZSH_VERSION-} ]]; then
    autoload -U +X bashcompinit && bashcompinit
fi

_foo()
{
    local cur="${COMP_WORDS[COMP_CWORD]}"
    local IFS=$'\n'
    w[0]='first '
    w[1]='second and space '
    w[2]='third\\ quoted\\ space '
    COMPREPLY=( $(compgen -W "${w[*]}" -- $cur) )
}
complete -o nospace -F _foo foo
---

The result in bash (by typing 'foo f<tab>', 'foo s<tab>', and so on) is:

'foo first '
'foo second and space '
'foo third\ quoted\ space '

In zsh, the results are quite different:

'foo first\ '
'foo second\ and\ space\ '
'foo third\ quoted\ space\ '

The following patch improves the results for me, but I get 'foo
third\\ quoted\\ space ', which is still not correct.

Any ideas?
