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.

@quotation
  Most of the XEmacs text editor is written in the programming
language called XEmacs Lisp.  You can write new code in XEmacs Lisp and
install it as an extension to the editor.  However, XEmacs Lisp is more
than a mere ``extension language''; it is a full computer programming
language in its own right.  You can use it as you would any other
programming language.

  Because XEmacs Lisp is designed for use in an editor, it has special
features for scanning and parsing text as well as features for handling
files, buffers, displays, subprocesses, and so on.  XEmacs Lisp is
closely integrated with the editing facilities; thus, editing commands
are functions that can also conveniently be called from Lisp programs,
and parameters for customization are ordinary Lisp variables.

  This manual describes XEmacs Lisp.  Generally speaking, the earlier
chapters describe features of XEmacs Lisp that have counterparts in
many programming languages, and later chapters describe features that
are peculiar to XEmacs Lisp or relate specifically to editing.
