Track down and fix more unbalanced QuoteLinks. #2893

Closed linas closed 2 years ago

linas commented 2 years ago

This fixes all of them, except for on that is intentionally unbalanced in a unit test.

@ngeiswei There are still many unbalanced QuoteLinks in the URE code base. These can be found by stopping the debugger at STRICT_QUOTATION_LEVEL in Quotation.cc I don't know that it matters very much. The unbalanced quotes might be hiding more serious bugs .. or maybe not. The unit tests do pass...

p.s. this is continuing fallout from #2886 .. which was fixed yesterday. This pull req just tracks down and fixes more cases that don't seem to actually affect anything.
