Subject: checkpatch: improve SUSPECT_CODE_INDENT test
Many lines exist like
if (foo)
bar;
where the tabbed indentation of the branch is not one more than the "if"
line above it.
checkpatch should emit a warning on those lines.
Miscellenea:
o Remove comments from branch blocks
o Skip blank lines in block
