I've completed it with these changes:
	- remove spaces before tabs in libs
	- remove more trailing spaces in non-C files

Applied for version 1.7.0.

Some whitespaces and indentation errors are remaining, especially in examples.
But it can be fixed when examples will be updated.
I'm not a big fan of such patch. I prefer to take care of not adding new
spacing errors. So from now, trailing whitespaces, spaces before tabs
and wrong indentation should be tracked carefully in new patches.

Thanks
