Formatting differs in section with no blank lines whether or not keepBlankLines is used

[thekalla]

The formatting output differs whether keepBlankLines and thus the BlankLinesWriter is used or not

Original unformatted xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <test>${project.build.directory}/reports/json/
    </test>
</project>

Format with keepBlankLines=false

Output:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <test>${project.build.directory}/reports/json/</test>
</project>

Format with keepBlankLines=true

Actual:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <test></test>
</project>

Expected:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <test>${project.build.directory}/reports/json/</test>
</project>

What is going on here is that its taking the line ${project.build.directory}/reports/json/\n to process, since that contains the check for \n, it is considered to be skipped and it continues to next token which there will not be one. Thus it skips printing that entirely as indicated. What it should be doing is checking that it even has more tokens to process. If it does not, it needs to continue on as it normally does so it does not skip writing data.

I'm working on a fix now including adding this example as a test case now.
