Subject: (read_process_output): Don't call setup_coding_system
X-Git-Tag: emacs-20.1~893
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=77e1b3d494eed714f22f8b18c9d87bdd2fb3f890;p=emacs.git

(read_process_output): Don't call setup_coding_system
for proc_decode_coding_system[channel].  It is already done in
detect_coding called via decode_coding.

(wait_reading_process_input): Call detect_input_pending
whenever read_kbd is 0, not just when wait_for_cell.
