master dc3b3548b7c: * lisp/composite.el (compose-gstring-for-terminal): Fix omitted var.

commit dc3b3548b7cd2a2170dd24d3cd8199bd9688276f

    * lisp/composite.el (compose-gstring-for-terminal): Fix omitted var.
    
    It may not make much of a difference since the code path is probably
    only taken once for i=0 with no more glyphs in the input, but this
    change avoids depending on such external invariants and makes
    the code less mystifying to the reader (bug#63807).
