A skeleton is basically a list.  Each element of the list is either a
string, a piece of lisp code, a sub-skeleton list or something to be
reinterpreted by skeleton-internal-1, basically anything that lisp
allows as a list member.  The only reason a bare - would occur in an
existing skeleton is if someone was using it as a variable name for some
obscure purpoose.  It is quite unlikely that any existing skeleton has
any bare -'s, the only use would be as parts of strings or character
constants using the usual lisp syntax for such.
