Subject: * lisp/composite.el (compose-gstring-for-terminal): Fix omitted var.
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=dc3b3548b7cd2a2170dd24d3cd8199bd9688276f;p=emacs.git

* 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).
