The previous version was returning 3 (mount point) even if the dir
contains something after the lost+found directory. I think this case
deserves a 4 output. For example:
lost+found
zzz.txt
give the result 3.
If the directory contains
aaa.txt
lost+found
the result is instead 4.
This doesn't make much difference, as 3 and 4 are both error condition
for all the callers, but the current behavior looks odd to me, and
surely is not what one can expect reading the comments.
My version returns 3 only if the lost+found file is alone in the
directory (eventually ignoring dot files along it, as it was doing before)

Marco
