Fix Lindent to not indent preprocessor comments so far

I recently ran Lindent over the AdvanSys driver and it moved the
comments on #else and #endif lines way over to the right:

	#else                          /* ADVANSYS_DEBUG */

This doesn't match what I expect from kernel style, but it is
documented.  We just need another flag to indent to make this look like:

	#else /* ADVANSYS_DEBUG */
