Description

As part of looking into creating a patch for MRELEASE-477, I realized that SCM providers would need to indicate whether they are able to create a "tag" directly from a modified working copy. Subversion can do this, but not all providers can. I'm providing a patch that adds a requiresCommitBeforeTag() method to ScmProvider, similar to the requiresEditMode() method. It looks like there is a request for a general "capabilities" API in SCM-23; this would fit into such an API if it existed, but that issue doesn't have a patch attached

I haven't provided a test of this since it's only a flag that is not used inside maven-scm (I'm planning to provide a patch for maven-release to use it there). I could see it being used in scm:tag to allow a generic check for a dirty working copy in a local-to-remote tag operation, but it seems like these things are better handled by the provider themselves.
