 No warnings or error messages are printed while @var{body} is
 executing.  If an error does occur during the execution of @var{body},
-@var{cleanup} can access the text of the message that would have been
-printed in the builtin constant @code{__error_text__}.  This is the same
-as @code{eval (@var{try}, @var{catch})} (which may now also use
-@code{__error_text__}) but it is more efficient since the commands do
-not need to be parsed each time the @var{try} and @var{catch} statements

 Octave's @var{try} block is a very limited variation on the Lisp
 condition-case form (limited because it cannot handle different classes
