Thanks.

Allow me a few comments:

> +of the variables; a value of 1 or @code{--all-values}, prints also

It would be much simpler to rephrase like this:

   Display the local variable names for the current frame.  If
   @var{print-values} is 0 or @code{--no-values}, print only the names
   of the variables; if it is 1 or @code{--all-values}, print their
   values as well; if it is 2 or @code{--simple-values}, print ...

you get the point.  Note that I also changed "prints" -> "print",
since the sentence before that says "Display", not "Displays".

I think the GNU project's convention is not to use "he" where "she" is
also possible.

This could also use similar rephrasing.

> -A @samp{*} causes all existing variable objects to be updated.
> +A @samp{*} causes all existing variable objects to be updated.  

These two lines are identical, except that the second one has 2
trailing blanks.  Please remove those blanks.

> +The option @var{print-values} determines whether names and values, or
> +just names are printed in the manner described for @code{-var-list-children}.

Please add a cross-reference here that points to the description of
"-var-list-children".  (Since the commands don't have each one its own
node, you will have to use @anchor to create a point-able place for
the xref.)
