thanks again, pushed to master.

much better, though there was still a DBGUTIL-only place left...

i wondered about the copy constructor that you removed in patch #1,
which was pretty horrible (i mean the copy ctor, not your removal), and
worried that it may be automatically generated, but apparently it is
not, i get a compiler error when trying to invoke it.

also i tried to derive the class from boost::noncopyable, but ran into
surprising problems, namely that its base class SwClient is already
derived from boost::noncopyable, so GCC said:

direct base ‘boost::noncopyable_::noncopyable’ inaccessible in
‘SwAuthorityFieldType’ due to ambiguity

it is very surprising that it was possible to write a copy constructor
for this class before, investigation revealed that it did not invoke the
SwClient copy constructor, but another SwClient constructor (indirectly)...

more seriously is this in patch #5. tautofmt.cxx:

the boost::ptr_vector::erase deletes the element, so p is invalid.  have
tried to fix this with the boost::ptr_vector::transfer method.

also, patch #6 introduced a memory leak, because the SwTableLines member
needs to be explicitly cleaned up in the destructor now it is a std::vector.
