No.  It's a debugging artefact.  I intended to clean-up and wrap the
two clauses into a single statement

.    if !'\\n[.z]'LIST*DIV' \{\
.       if '\\*[pre-list-quad]'C' .nr #LIST_CENTER 1
.       if '\\*[pre-list-quad]'R' .nr #LIST_RIGHT 1
.       nr #PRE_LIST_QUAD \\n[.j]
.       di LIST*DIV
\!.     nr #IN_LIST 1
.       ad l
.    \}

I'll incorporate the change into my next commit.
