Re: [PATCH] config: fix several access(NULL) calls

Yes, but when $HOME is unset, the question doesn't really make sense.
Maybe the file exists, but we can't know since the user broke his
configuration by unsetting $HOME. The intent was to avoid writing to the
XDG file unless it was very clear that the user wanted it, so in doubt,
dying seems the best option.
