Make #'substring an alias of #'subseq; give the latter the byte code. src/ChangeLog addition: 2010-03-03 Aidan Kehoe <kehoea@parhasard.net> * fns.c (Fsubstring): Removed. * search.c (Freplace_match): * minibuf.c (Ftry_completion): * lisp.h: * keymap.c (ensure_meta_prefix_char_keymapp): * dired.c (user_name_completion, file_name_completion): * console-x.c (x_canonicalize_console_connection): * bytecode.c (Bsubseq): * bytecode-ops.h (subseq): Move #'substring to Lisp, as an alias for #'subseq; change all C Fsubstring() calls to Fsubseq(), change the Bsubstring bytecode to Bsubseq. Motivation; not accepting vectors in #'substring is incompatible with GNU, and Common Lisp prefers #'subseq, it has no #'substring. lisp/ChangeLog addition: 2010-03-03 Aidan Kehoe <kehoea@parhasard.net> Move byte code #o117 to #'subseq, not #'substring. Make #'substring available as an alias for #'subseq in Lisp. * bytecomp.el (79, subseq, substring): * bytecomp.el (byte-compile-subseq): New. * update-elc.el (update-elc-chop-extension): Use #'subseq, not #'substring, the latter is not yet available. * subr.el (substring): New alias, to #'subseq. man/ChangeLog addition: 2010-03-03 Aidan Kehoe <kehoea@parhasard.net> * lispref/tips.texi (Comment Tips): * lispref/text.texi (Text Properties): * lispref/strings.texi (Creating Strings): * lispref/processes.texi (Input to Processes): * lispref/functions.texi (Argument List): * lispref/extents.texi (Duplicable Extents): Move examples that used substring to using subseq; in strings.texi, do not change the examples, but document that in this XEmacs, it is an alias for subseq, and that there may be some incompatibilities if you depend on that.
