Subject: error in plot.formula(..., ask = FALSE) (PR#1923)

Passing ask = FALSE in plot.formula returns an error.

For example:
-------------------

dat <- data.frame(y  =            c(1,1,1,2,2,2,3,3,3,4,4,4), 
                  x1 = as.ordered(c(1,1,1,1,1,1,2,2,2,2,2,2)),
                  x2 = as.ordered(c(1,1,1,2,2,2,1,1,1,2,2,2)))

plot(y ~ x1 + x2, data = dat) # Works fine "interactively" asking:
# "Hit <Return> to see next plot:"
#  But this causes problems when it is run in a batch file.

plot(y ~ x1 + x2, data = dat, ask = FALSE) # gives error:
# "Error in model.frame(formula, rownames, variables, varnames, extras,
# extranames,  :   variable lengths differ"
