* xemacs/programs.texi (Defuns):
* lispref/variables.texi (Local Variables, Defining Variables)
(Setting Variables, Default Value):
* lispref/symbols.texi (Definitions):
* lispref/searching.texi (Saving Match Data):
* lispref/positions.texi (Excursions, Narrowing):
* lispref/objects.texi (Primitive Function Type):
* lispref/macros.texi (Defining Macros, Backquote):
* lispref/lispref.texi (Top):
* lispref/intro.texi (A Sample Function Description):

(Special Operators, Quoting):
* lispref/edebug-inc.texi (Instrumenting)
(Specification Examples):
* lispref/debugging.texi (Internals of Debugger):
* lispref/control.texi (Control Structures, Sequencing):
(Conditionals, Combining Conditions, Iteration):
(Catch and Throw, Handling Errors):
* lispref/commands.texi (Defining Commands, Using Interactive):
Terminology change; special operator -> special form.
Don't attempt to change this in texinfo.texi or cl.texi, which use
macros I don't understand.
* lispref/macros.texi (Defining Macros): Give an anonymous macro
example here.
* lispref/positions.texi (Excursions):
Correct some documentation that called a couple of macros special
forms.
* lispref/searching.texi (Saving Match Data):
Drop some documentation of how to write code that works with Emacs
18.
* lispref/specifiers.texi (Adding Specifications):
Correct this; #'let-specifier is a macro, not a special operator.
* lispref/windows.texi (Window Configurations)
(Selecting Windows):
Correct this, #'save-selected-window and #'save-window-excursion
are macros, not special operators.
lisp/ChangeLog addition:
2010-01-31 Aidan Kehoe <kehoea@parhasard.net>
* obsolete.el:
* loadhist.el (symbol-file):
* help.el (describe-function-1):
* bytecomp.el: (byte-compile-save-current-buffer):
* byte-optimize.el (byte-optimize-form-code-walker):
* subr.el (subr-arity):
Change "special form" to "special operator" in these files, it's
the more logical term.
* subr.el (special-form-p): Provide this alias for
#'special-operator-p.
