The current SUSPECT_CODE_INDENT test does not recognize several
defective code style defects where code following a logical test
is inappropriately indented.
Before this patch, for code like:
if (foo)
bar();
checkpatch would not emit a warning.
Improve the test to warn when code after a logical test has the
same indentation as the logical test.
Perform the same indentation test for "else" blocks too.
