[Doxygen-develop] xml & tab

[<ca...@cr...>]

	Hi, all again!
	Xml generator insert tab symbols direct into xml source (&example) =
output, thus there are no way to differ tab from space at XSLT =
transformation.
	Simple attached patch change tab to appropriated count of <sp/> tags in =
compliance with TAB_SIZE Doxyfile setting.
	Thanks, - Alexandr -
