Moved clearing of "literal" flag. The flag is set in setliteral which

can be called from a start tag handler.  When the corresponding end
tag is read the flag is cleared.  However, it didn't get cleared when
the start tag was for an empty element of the type <tag .../>.  This
modification fixes the problem.
