Yeah, and I should have though twice before doing so, too.

Because, after a while, I realizes that I had just screwed up my
entire completion setup. Stuff like 'git <tab>' started to act weird,
because all of a sudden, the _tilde at the start of my configured
completers tried to treat *everything* as a user name or hashed
directory...

So, I sat myself down and wrote up the following (it does something
special if $BUFFER is empty, too; that's an older idea):

[snip]
function ft-complete() {
    emulate -L zsh
    setopt extendedglob
    local action context widget word

    if [[ -z ${BUFFER} ]]; then
        context=empty
        zstyle -s ":zle:ft-complete:${context}" action action || action=empty
        zstyle -s ":zle:ft-complete:${context}" widget widget || widget=complete-word
        case ${action} in
            dot-slash-complete)
                BUFFER='./'
                CURSOR=2
                zle ${widget} -w
                ;;
            empty)
                ;;
            *)
                zle ${widget} -w
                ;;
        esac

        return 0
    fi

    word=${LBUFFER##* }
    if [[ ${word} == \~* ]] ; then
        context=tilde
        zstyle -s ":zle:ft-complete:${context}" widget widget || widget=complete-word
        zle ${widget} -w
        return 0
    fi
    context=default
    zstyle -s ":zle:ft-complete:${context}" widget widget || widget=complete-word
    zle ${widget} -w
    return 0
}

zle -N ft-complete
[snap]

And then I do this for configuration:

[snip]
zle -C ft-complete-tilde complete-word _generic
zstyle ':completion:ft-complete-tilde:*' completer _tilde _expand _complete _ignored _approximate

zstyle ':zle:ft-complete:tilde' widget ft-complete-tilde
[snap]

My main completer style now is this again:

    zstyle ':completion:*' completer _expand _complete _ignored _approximate

This seems to work rather nicely. Without screwing everything up in
the process. :-)

I just thought, I'd let people know before they waste time on trying
out my previous stupidities.
