Escape < and & in SGML

Browse Source 
This is not required in SGML, but will be in XML, so this is a step to
prepare for the conversion to XML.  (It is still not required to escape
>, but we did it here in some cases for symmetry.)

Add a command-line option to osx/onsgmls calls to warn about unescaped
occurrences in the future.
