Subject: [PATCH] Issue #230: Need to KEEP this newline char sometimes.

This is a case where the lexer, in GetTokenfromStream, does NOT eat any
trailing newline after a LEX_STARTTAG: case...

So far have identified pre, script, style as NEEDING this user newline
character for later pprint output. Any others?
