Eli asked me to use --with-values for -var-update.  Since, after the change,
-stack-list-locals would have the same options, I thought they should have
the same names. FWIW my preference is the same as yours: to use --all-values
throughout.

-var-list-children --all-values VARNUM      works with 6.3.

-var-list-children --with-values VARNUM     would work with 6.4 if these
                                            changes are installed.

-var-list-children 1 VARNUM                 would work with 6.3 and 6.4 if
                                            these changes are installed.
