ESPIPE error in 4.2

[colonel at gloria.UUCP]

[also, why can't I execute a character special file?]

In 4.2bsd, lseek() on a pipe seems to return EINVAL instead of ESPIPE.
This breaks things like

	echo abcde | tail +3c

Fortunately, it looks like a simple fix - change one word in
ufp_syscalls.c.

	Does anybody have any arguments AGAINST fixing it this way?
