It's not like it's not _documented_ or anything. From the read(2) manpage:
RETURN VALUES
If successful, the number of bytes actually read is returned. Upon read-
ing end-of-file, zero is returned. Otherwise, a -1 is returned and the
global variable errno is set to indicate the error.
The problem is that the losers who wrote the stuff never bothered to
test for this; they expect an error condition on stdin instead.
The correct fix is for you to hunt down all the places in the offending
programs where read() is called on stdin and patch them to check for '0'
return, and then pester the maintainers and forward patches to the ports
people.
Otherwise this will never be fixed.
