Simplify the API of PARSE_KEYWORDS for callers. src/ChangeLog addition: 2010-09-18 Aidan Kehoe <kehoea@parhasard.net> Simplify the API of PARSE_KEYWORDS for callers. * lisp.h (PARSE_KEYWORDS): Simply the API, while making the implementation a little more complex; work out KEYWORDS_OFFSET from the appropriate Lisp_Subr struct, take the function name as the C name of the DEFUN rather than a symbol visible as a Lisp_Object, on debug builds assert that we're actually in the function so we choke on badly-done copy-and-pasting, * lisp.h (PARSE_KEYWORDS_8): New. This is the old PARSE_KEYWORDS. * fns.c (Fmerge, FsortX, Ffill, Freduce, Freplace): Change to use the new PARSE_KEYWORDS syntax. * elhash.c (Fmake_hash_table): Chance to the new PARSE_KEYWORDS syntax, rename a define to correspond to what other files use. * symbols.c (intern_massaging_name): * buffer.c (ADD_INT): Rename intern_converting_underscores_to_dashes() to intern_massaging_name(), now it does a little more.
