 There are lots of things wrong with POSIX; it would be nice in theory
 (although I doubt anyone reading this has the time or energy) to
 collect them up somewhere for reference.
 
 The shell-related thing I've run across is that the behavior
 specification for -e mode is so poorly written that it's nearly
 impossible to tell what it's supposed to be, let alone test any given
 implementation for conformance. And some of the parts that are clear
 are at variance with common sense and historical practice.
 
 NetBSD is in general more committed to maintaining historical practice
 (and to correctness) than to strict compliance. And since the POSIX
 folks seem to be running somewhat off the track lately (e.g. on
 getline) I suspect that we will start to diverge somewhat more from
 conformance too...
