[BZ #4745]

	* stdio-common/vfscanf.c (_IO_vfscanf): Add additional test for EOF
	in loop to look for conversion specifier to avoid testing of
	wrong errno value.
	* stdio-common/Makefile (tests): Add bug18, bug18a, bug19, bug19a.
	* stdio-common/bug18.c: New file.
	* stdio-common/bug18a.c: New file.
	* stdio-common/bug19.c: New file.
	* stdio-common/bug19a.c: New file.
