check-code: explain what to do when a check-code rule mismatches

In the past several approaches were used when a check-code rule triggered
without a good reason. Not all of them looked nice, some were even wrong.
Suggest some good practices which should be used instead.

+when a rule triggers wrong, do one of the following (prefer one from top):
+ * do the work-around the rule suggests
+ * doublecheck that it is a false match
+ * improve the rule pattern
+ * add an ignore pattern to the rule (3rd arg) which matches your good line
+   (you can append a short comment and match this, like: #re-raises, # no-py24)
+ * change the pattern to a warning and list the exception in test-check-code-hg
+ * ONLY use no--check-code for skipping entire files from external sources
