Linux users like to sneer at Windows users for believing that Windows is 
a synonym for "computer", that what Windows does is what all computers 
do, but Linux users (especially if they're also C programmers) sometimes 
have a hard time remembering that "what POSIX does" is no more a 
universal limitation on computing than "what Windows does".

(And ironically, Linux doesn't even have POSIX certification.)

That is, when they're not blindly writing shell scripts using bashisms 
and expecting them to work under any shell :-)


I still would like to see one real-world use-case where the distinction 
between "file name is invalid because it has NUL" and "file name is 
invalid for any of a dozen other reasons" is necessary and important.
