Hi all (who remain true to the cause :-),
I cam across a bug in cifs.
An empty directory under windows 7 pro contains a single entry "." but it
doesn't appear to contain "..".
As a result "." is not removed on dirscan and plan9 gets when trying to
traverse the hierarchy.

< if(got >= 2 && strcmp(fi[0].name, ".") == 0 &&
< strcmp(fi[1].name, "..") == 0){

< memmove(a->cache, a->cache + sizeof(FInfo)*2,
< a->end - a->off);
