Code this up in a simplistic manner (i.e. using a FileReader and a regexp) we can always make it smarter if we need to.
Initially I made this a deprecation warning, but I am unsure about the error message

WARN [DEPRECATED:125] - Java class 'net.shibboleth.ext.spring.context.DeferPlaceholderFileSystemXmlWebApplicationContext', (edit-webapp/WEB-INF/web.xml): This will be removed in the next major version of this software; replacement is net.shibboleth.ext.spring.context.DelimiterAwareApplicationContext

I’ll change this because in fact the situation is more severe you *have* to replace it and rerun the build
