Subject: (encode_terminal_code): Adjusted for the change of struct
X-Git-Tag: emacs-pretest-23.0.90~3169
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=75a1078622818d6eaa5c98d50cabc8685eb8d3c7;p=emacs.git

(encode_terminal_code): Adjusted for the change of struct
glyph.
(append_composite_glyph): Adjusted for the change of struct it and
struct glyph.
(produce_composite_glyph): Likewise.
