* 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/bug18a.c: New file. * stdio-common/bug19.c: New file. * stdio-common/bug19a.c: New file.
