Typically, src/SvnRev.h should be updated with each commit, that's
right. Note, however, that there are some commits to the svn repository
that don't affect the code (e.g. changes to the wiki, AFAIK). So the
actual (global) svn revision number can differ from the revision at
which the code was last changed.

As stated before, getSvnRev.sh can't always be run (e.g. it fails on
Windows or when the code is exported from svn to some packaging tools).
Hence src/SvnRev.h must be retained (though it could be changed to use
svn keywords, for example).

Unfortunately, this doesn't hold for some other platforms/packaging tools.
