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.

168 In this implementation, @code{substring} is an alias for @code{subseq},
169 so @var{string} can be any sequence. In GNU Emacs, @var{string} can be
170 a string or a vector, and in older XEmacs it can only be a string.
