[PATCH 6/6] CMD.EXE: Partially fix 'dir *.' (ie files with no extension)

[Jason Edmeades]

Note: This exposes a bug in the findfirst/findnext implementation
when *. is passed as a parameter:

The following test pgm shows this up:
void main() {
    WIN32_FIND_DATA fd;
    HANDLE hff = FindFirstFile ("*.", (&fd));
    char cmd[123];
    do {
        printf("%s\n", fd.cFileName);
    } while (FindNextFile(hff, &(fd)) != 0);
}

It lists limited files on windows, and all files on wine
(filed as bug#7961)
