* 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).
