Log Message:
lint: fix strange message about nested '==' operators

If one of the nested subexpressions is parenthesized, the author
probably knew how these expressions are evaluated.  Therefore don't warn
in such a situation.

Maybe the original author once made a typo and tried to initialize
variables but instead compared them, like this:

        int a, b, c;

        a == b == c;

This would explain the text of the message, which still sounds strange.
At least it doesn't show up as often anymore.
