Nothing big really, just things that tend to annoy you if you have to
work with the code and are not as much into it as you probably are.
Where to find the implementation of a function (often, only a grep -r
helps), why is it parser/parse_*.c but parser/msg_parser.c, stuff like
that. Sometimes, there are surprises. Like, in module functions, 0 is
TRUE, -1 is FALSE, and >0 is "exit" which is contradicting the usual
call conventions.

Oh, and if you all could agree on a tab length or only use tab for code
level indentation but not for aligning hanging blocks, I would be
grateful. cfg.y used to be a very bad example, but it is much better
now.

Have you ever tested whether the "standard" implementation imposes a
performance penalty? Off of my head I would say, no, at least not a big
one. But it remains to remain be seen.
