Fix bugs with #'find-file, 0-length files, & coding-system-for-read specified. src/ChangeLog addition: 2009-07-11 Aidan Kehoe <kehoea@parhasard.net> * file-coding.c (undecided_canonicalize_after_coding): If no data have been seen, or if coding_stream_canonicalize_after_coding gives nil, pass back str->codesys, which will be of type undecided (the same as the old behaviour) but will reflect any CODESYS argument passed to make_coding_input_stream. See also the change in lisp/code-files.el lisp/ChangeLog addition: 2009-07-11 Aidan Kehoe <kehoea@parhasard.net> * code-files.el (insert-file-contents): Take advantage of more sensible behaviour from #'insert-file-contents-internal, allowing us to actually follow the documented coding system behaviour for nonexistent files (that is, buffer-file-coding-system reflects coding-system-for-read &c., not becoming undecided for either zero-length or nonexistent files). tests/ChangeLog addition: 2009-07-11 Aidan Kehoe <kehoea@parhasard.net> * automated/mule-tests.el: Check for Richard Zidlicky's bug of http://mid.gmane.org/20090602194123.GA5163@linux-m68k.org; also check that supplying CODESYS to #'find-file is respected both for nonexistent files and zero-length existing files.
