Change "special form" to "special operator" in the manuals, too 2011-03-01 Aidan Kehoe <kehoea@parhasard.net> * lispref/commands.texi (Using Interactive): * lispref/compile.texi (Eval During Compile): * lispref/compile.texi (Compiled-Function Objects): * lispref/control.texi (Sequencing): * lispref/control.texi (Conditionals): * lispref/control.texi (Combining Conditions): * lispref/control.texi (Iteration): * lispref/control.texi (Catch and Throw): * lispref/control.texi (Handling Errors): * lispref/control.texi (Cleanups): * lispref/display.texi (Temporary Displays): * lispref/eval.texi (Quoting): * lispref/eval.texi (Multiple values): * lispref/frames.texi (Input Focus): * lispref/functions.texi (Argument List): * lispref/functions.texi (Defining Functions): * lispref/functions.texi (Anonymous Functions): * lispref/internationalization.texi (Level 3 Primitives): * lispref/internationalization.texi (Domain Specification): * lispref/intro.texi (A Sample Function Description): * lispref/intro.texi (A Sample Variable Description): * lispref/lists.texi (Sets And Lists): * lispref/macros.texi (Defining Macros): * lispref/macros.texi (Backquote): * lispref/positions.texi (Excursions): * lispref/positions.texi (Narrowing): * lispref/searching.texi (Saving Match Data): * lispref/sequences.texi (Sequence Functions): * lispref/sequences.texi (Array Functions): * lispref/specifiers.texi (Adding Specifications): * lispref/variables.texi (Local Variables): * lispref/variables.texi (Defining Variables): * lispref/variables.texi (Setting Variables): * lispref/variables.texi (Default Value): * lispref/windows.texi (Selecting Windows): * lispref/windows.texi (Window Configurations): No longer use @defspec, since we no longer use the term "special form"; instead use @deffn {Special Operator}. Unfortunately there's no way in texinfo to redefine @defspec in one place.
