scm plugin does not respect maven aggregation specifications

Good morning,

According to http://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Aggregation documentation, "the parent project now knows its modules, and if a Maven command is invoked against the parent project, that Maven command will then be executed to the parent's modules as well".

But it doesn't work for maven-scm-plugin.

Consider you have this kind of project

myProject
 |-- my-module
 |   `-- pom.xml
 `-- pom.xml

And you have set a "project.scm.connection" xml element in each pom.xml file.

if you run scm:checkout goal in parent project (myProject in above example), il will not run this goal in module (my-module in above example) but only in parent project.

Kind Regards,
Thomas.
