one question about Freebsd subversion access log

[Yiru Li]

Hello,
I am doing an analysis on Freebsd subversion access log. One log 
extracted from the access log is below.

The piece of log include files and subdirectories which are indicated 
"modified" (M).
The subdirectories are:
/stable/7/sbin/geom, /stable/7/sbin/geom/class/label,
/stable/7/sbin/geom/class/part
/stable/7/sbin/geom/class/stripe
/stable/7/sbin/geom/misc
/stable/7/sys
/stable/7/sys/cddl/contrib/opensolaris
/stable/7/sys/contrib/dev/acpica
/stable/7/sys/contrib/pf

My question is: why are the subdirectories recorded as "modified", even 
though there is no files modified under most of the subdirectories?

I did a test of modifying a file and submitting a commit to the 
subversion in my local machine. No subdirectories are recorded as 
"modified" except for the file.

I can not find the answer through googling.
thanks
Yiru
