\arguments{
\item{term}{a formula or piece of a formula}
\item{debug}{(logical) debug?}
\item{specials}{list of special terms}
\item{default.special}{character: special to use for parenthesized terms - i.e. random effects terms with unspecified structure
1. atom (not a call or an expression): NULL
2. special, i.e. foo(...) where "foo" is in specials: return term
3. parenthesized term: \emph{if} the head of the head is | (i.e.
it is of the form (xx|gg), then convert it to the default
special type; we won't allow pathological cases like
((xx|gg)) ... [can we detect them?]}
