Well, it's a well known issue, although I'm not sure it's filed in the
database at the moment (I tried to find it but couldn't).
What happens is this:
- The timestamp changes
- 'svn status' detects the timestamp differs from the one 'on file'
- 'svn status' sees the file has the "Id" svn:keyword set
- 'svn status' "translates" the working copy file to its repository normal form
for the "Id" keyword (which is $Id$)
- after translating the working copy file, it compares the base and
canonical wc files, finding that one has $Id:$ and the other $Id$,
hence they differ
You can achieve the same thing in 'original' by making sure the
