Subject: (Finsert_file_contents): Set coding_system to Qnil
X-Git-Tag: emacs-pretest-23.0.90~8295^2~1864^2~951
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1c157f8ddc376ed384e7c990c80de72dea23bd3e;p=emacs.git

(Finsert_file_contents): Set coding_system to Qnil
earlier.  If inserted is zero and the coding system doesn't
require flushing, don't call decode_coding_gap.
