This SVN-specific keyword [1] did not expand as expected on Git
repositories migrated from SVN via git-svn(1) [2]. Because of this,
applying patches with modifications would sometimes fail because, even
if these lines were not modified, they could be part of the context
lines, thus heavily confusing Git.
Since it is already expected to migrate from SVN to Git sometime soon,
this would also make $Id$ redundant.
