Default delimiters break filtering

As I upgraded the maven-resources-plugin to version 2.4.1 (version 2.3 has a major issue concerning windows paths, see http://jira.codehaus.org/browse/MRESOURCES-81), I'm facing another problem with default filtering delimiters.

If one of the resources contains a delimiter character that is not part of an expandable expression, then all of the following expandable expressions after the character will not be processed.

You can reproduce this using a resource property file that contains the default '@' character delimiter:

Contact: ${pom.name}@mycompany.com
URL: ${pom.url}
Version: ${pom.version}

Processing the project resources with Maven will produce:

Contact: myapp@myorganization.com
URL: ${pom.url}
Version: ${pom.version}

If the '@' delimiter character is removed, then it produces a correct output:

Contact: myappmycompany.com
URL: http://maven.apache.org
Version: 1.0

I tried to configure the plugin but it seems that I'm not able to redefine/disable/remove the default delimiters.
This bug was not present in version 2.3 but, as said before, this version has know bugs with windows paths (even if I hope that in future releases, my application will no more reference windows paths...).

Thanks for your support!
