Hi list.
Here's what I mean:
1) a created a git repo from a foreign source using git fast-import
2) new commits were added to the foreign source

Can I create a fast-import input stream not containing the commits
already existing in my git repo and import it?

I tried to create such streams with:
    cvsps --fast-export -d ...
and from a shallow git repo, but the new commits are not imported
(unless the import stream contains a new branch)
