dotgit's handling of a changing filelist has become "smarter" in the sense that merges will now be checked with the user example
foo:host1 ---> foo:host1,host2
foo:host2
The user would be asked what version the new combo should use. Splitting up a combo also now provides a copy for each split.
The default commentary char has also changed from // to to follow convention. Your filelist will be automatically updated when you run the new dotgit for the first time.
