----------------------------+-------------------------
 We should have a pre-commit hook in the Subversion repository to prevent
 expanded keywords from being committed. That is, if a file has
 svn:keywords set to "Id", it should not be possible to commit the file
 with contents like this:

 {{{
 $Id: anything $
 }}}

 The Subversion client is responsible for normalizing this before
 committing to:

 {{{
 $Id$
 }}}

 The problem is that some committers use non-standard Subversion clients
 like git-svn that do not respect this requirement. This could have
 unforeseen consequences and should be prevented.

 I will work on writing this pre-commit script. It could be combined with
 the one needed for #12594.
