Only valid for the first commit made on this branch by this -fast-import process. The from command is used to specify the commit -to initialize this branch from. This revision will be the first -ancestor of the new commit.
-Omitting the from command in the first commit of a new branch will -cause fast-import to create that commit with no ancestor. This tends to be -desired only for the initial commit of a project. Omitting the -from command on existing branches is required, as the current -commit on that branch is automatically assumed to be the first -ancestor of the new commit.
