Subject says it all. Thanks!
It looks like Fossil's command line tools need some work. Diffuse needs to discover some information about the local checkout through the revision control system's command line tools. Fossil reports confusing file status when files are renamed. This causes problems for the "-c" and "-m" command line options (and associated menu items). When files are renamed, Diffuse needs to discover the old name of the file and be able to retrieve its contents. Diffuse also needs to find the parent for a named revision. Any idea on how to retrieve this information from Fossil's command line tools?
