svn:keywords can't be ignored in Subversion (at least I don't know of
a way to ignore them).
+Renamed and copied directories are not detected by git and hence not
+tracked when committing to SVN. I do not plan on adding support for
+this as it's quite difficult and time-consuming to get working for all
+the possible corner cases (git doesn't do it, either). Renamed and
+copied files are fully supported if they're similar enough for git to
+detect them.
