Use better types when ESCAPECHAR is specified, split_string_by_ichar_1 src/ChangeLog addition: 2010-02-19 Aidan Kehoe <kehoea@parhasard.net> * fns.c (split_string_by_ichar_1): Use better types (e.g., not an Ichar for a buffer size) in this function when dealing with ESCAPECHAR. tests/ChangeLog addition: 2010-02-19 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Change the #'split-string-by-char text to use US federal government information instead of a couple of sentences from the OED; the latter would probably have qualified as non-infringement, but with the former the question won't arise. (The German text in the same tests is from a very public domain 19th-century work.)
