Bug in doincludes function

[amirtadayon]

Let's say we want to jemdoc the file, bug.jemdoc, which contains an instance of includeraw.
There is no whitespace / newline after the #includeraw{patent.html}. When jemdocing this file, an error is raised saying that there is not patent.html file. A quick fix can be found in PR here

bug.jemdoc file

# jemdoc: {bug.html}
= Bug reproduce in doincludes \n

== Patent
#includeraw{patent.html}

No newline/whitespace at the end of file.
