svn diff/patch change file permission in cad/feappv

[Anton Shterenlikht]

I'm updating cad/feappv.
I noticed that svn diff, followed by svn patch
changes file permissions for 2 files out of 3.
Please help

After I finished updating the port, I did:

# pwd
/usr/ports/cad/feappv
# ls -al

Note that now Makefile and distinfo have 600 perms,
instead of 644. Have I missed some svn diff/patch
option? Or is there a reason for the change in permissions?

Thanks
