Exercise in matching rules: sub= matches *subset* in the definition of

One way out is to use the format


another is to change the definition of boxplot.formula() so that the
'...' goes immediately after the formula argument, which will force
all argument matches to be exact and non-positional.

There's a deep code freeze on 1.0.0, so it cannot be fixed now, but
it might go into 1.0.1.
