Render of tabs within code is not correct.

[heckl]

I am using the latest notepad++, and lthe atest viewer plugin.

My file contains some code:

		<parser
			id         ="txt_Heckl_syntax"
			displayName="txt_Heckl_syntax"> 
			<function mainExpr="^(H1|H2|H3|H4|H5).*$">
			</function>
		</parser>  

The tabs are rendered as spaces (or very short tabs) in the view panel. The html export works as expected.
