Why is that?

Looking at this code made me notice that the filename completion doesn't
handle the EAGAIN case like directory-files does. And also that
directory-files doesn't check QUIT if it had been interrupted, which can
fail to react to C-g in cases such as SYNC_INPUT.
So I've installed the patch below.

If the NFS server is down, I suspect that either call can stall.
