If you are talking about an interactive shell reading input with ZLE, you
can do it with "zle -U".
If you're in some other way reading from a stream such as standard input,
unget is not possible. You need a lower-level programming language with
more direct control over things like stdio buffers. (Unget is not an OS-
level operation, it's implemented in stdio or the equivalent.)
