I guess someone might want 'M-z' to quit isearch and zap to the next char.

BTW, should the new command use the same function arguments '(arg char)'
to be more compatible with 'zap-to-char'?

Also I tried 'M-z <SPC>' at the end of the buffer and it raises the same error:

  Debugger entered--Lisp error: (search-failed " ")
    search-forward(" " nil nil 1)
    zap-to-char(1 32)
    funcall-interactively(zap-to-char 1 32)
    call-interactively(zap-to-char nil nil)
