@ -4002,6 +4002,16 @@ when using an action of the form `tt(->)var(string)'. With this
function the tt(context) parameter will be set to the name of the
value whose argument is to be completed.
Note also that tt(_values) normally adds the character used as the
separator between values as a auto-removable suffix so that users don't
have to type it themselves. But when using a `tt(->)var(string)' action
tt(_values) can't do that because the matches for the argument will be
generated by the calling function. To get the usual behaviour, the
implementor of the calling function has to add the suffix directly by
passing the options `tt(-qS) var(x)' (where var(x) is the separator
character specified with the tt(-s) option of tt(_values)) to the
function generating the matches or to the tt(compadd) builtin.
Like tt(_arguments), tt(_values) supports the tt(-C) option in
which case you have to make the parameter tt(curcontext) local instead
of tt(context) (as described above).
