Comment (by ecronin@…):

 In pure git you can't do keyword substitution, but git-svn is a bridge
 between a local git repo and a remote svn repo and can perform
 translations as changes go from one to the other.  Recent versions of git-
 svn compress the expanded keyword down to just the $Id$ marker before
 creating the commit object in git. It is ignored and left alone during all
 git operations, but then gets expanded back out properly by svn on
 dcommit.  It's a little annoying because locally you don't have the Id
 info in the file so you have to use git log, but it shouldn't be causing
 issues with svn. I have no idea when it was added to git-svn, it's worked
 fine for at least a year for me. Setting the svn attributes to begin with,
 however, I think you still have do using a svn checkout. And I haven't
 found a way to turn a git mv into a svn mv that maintains history.
