c589e97563 Fix PR c/69122 (-Wmisleading-indentation false positive with empty macros)
gcc/c-family/ChangeLog:
	PR c/69122
	* c-indentation.c (get_visual_column): Remove default argument.
	(should_warn_for_misleading_indentation): For the multiline case,
	update call to get_visual_column for next_stmt_exploc so that it
	captures the location of the first non-whitespace character in the
	relevant line.  Don't issue warnings if there is non-whitespace
	before the next statement.

gcc/testsuite/ChangeLog:
	PR c/69122
	* c-c++-common/Wmisleading-indentation.c (pr69122): New function.
