Description Yoshihiko Sarumaru 2005-01-17 07:30:24 UTC 
	The feof(3) tells that "The end-of-file indicator can only be cleared by the function clearerr()."
	But fseek(fp, 0, SEEK_SET) or writing extra bytes to the stream can clear the EOF indicator, too.

	POSIX (SUSv3) doesn't mention about it.

Fix: This patch is for RELENG_4 (1.3.2.4) ferror.3, sorry.
How-To-Repeat: 	man 3 feof
