Subject: * io.c (rb_io_s_pipe): accept optional hash.   (rb_io_set_encoding):
 ditto.   (rb_io_extract_modeenc): use rb_econv_opts to initialize   ecopts.  
 (rb_file_open_generic): ditto.   (rb_file_open_internal): ditto.  
 (io_encoding_set): new argument: opt.   (argf_set_encoding): copy
 fptr->encs.opts to argf_ecopts.

* transcode.c (rb_econv_opts): accept Qnil for initialization.
