Make Lisp reader errors more informative with over-long hex, octal characters src/ChangeLog addition: 2010-08-21 Aidan Kehoe <kehoea@parhasard.net> * lread.c (read_escape): Make error messages better reflect the text that was encountered, when overlong hex character escapes or non-Latin-1 octal character escapes are encountered. man/ChangeLog addition: 2010-08-21 Aidan Kehoe <kehoea@parhasard.net> * lispref/objects.texi (Character Type): Go into more detail here on the specific type of error provoked on overlong hex character escapes and non-Latin-1 octal character escapes; give details of why the latter may be encountered, and what to do with such code.

@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.
