PR c/66220:
* c-indentation.c (should_warn_for_misleading_indentation): Use
expand_location rather than expand_location_to_spelling_point.
Don't warn if the guarding statement is more indented than the
next/body stmts.
gcc/testsuite/ChangeLog:
PR c/66220:
* c-c++-common/Wmisleading-indentation.c (fn_35): New.
