Will this work for -x and -X? I requested earlier to make -X/x support
special outputs in order to avoid fork and you only mentioned what
would be needed to make this work. I was looking at printf
implementation and noticed many special cases and have chosen to
request the feature instead of implementing it. If now -x/X will work
with -v it will be great news to me because I will be able to quickly
expand tabs =E2=80=93 without a fork or plain Zsh code.
