Quite some time ago (r184879) I reformatted the entry for the i386 
-mrecip= option as part of a general cleanup of that section.  Here's 
the corresponding change for the very similary RS/6000 option, which 
I've committed as an "obvious fix".

 This option controls which reciprocal estimate instructions
 may be used.  @var{opt} is a comma-separated list of options, which may
 be preceded by a @code{!} to invert the option:
-@code{all}: enable all estimate instructions,
-@code{default}: enable the default instructions, equivalent to @option{-mrecip},
-@code{none}: disable all estimate instructions, equivalent to @option{-mno-recip};
-@code{div}: enable the reciprocal approximation instructions for both single and double precision;
-@code{divf}: enable the single-precision reciprocal approximation instructions;
-@code{divd}: enable the double-precision reciprocal approximation instructions;
-@code{rsqrt}: enable the reciprocal square root approximation instructions for both single and double precision;
-@code{rsqrtf}: enable the single-precision reciprocal square root approximation instructions;
-@code{rsqrtd}: enable the double-precision reciprocal square root approximation instructions;

+@item default 
+Enable the default instructions, equivalent to @option{-mrecip}.

 So, for example, @option{-mrecip=all,!rsqrtd} enables
 all of the reciprocal estimate instructions, except for the
