It was suggested on the mailing list that being able to use `from` in any commit to reset the current branch is useful in some types of importers, such as a darcs importer. We originally did not permit resetting an existing branch with a new `from` command during a `commit` command, but this restriction was only to help debug the hacked up cvs2svn that Jon Smirl was developing in parallel with git-fast-import. It is probably more of a problem to disallow it than to allow it. So now we permit a `from` during any `commit`. While making the changes required to permit multiple `from` commands on the same branch, I discovered we no longer needed the last_commit field to be set to 0 during a reset, so that was removed. (Reset was originally setting the field to 0 to signal cmd_from() that it was OK to execute on the branch.) While poking around in this section of fast-import I also realized the `reset` command was not working as intended if the corresponding `from` command was omitted (as allowed by the BNF grammar and the code). If `from` was omitted we cleared out the tree but we left the tree SHA-1 and parent commit SHA-1 intact. This is not what the user intended in this case. Instead they would be trying to reset the branch to have no parent and to have no tree, making the branch look new-born during the next commit. We now clear these SHA-1 values during `reset`, ensuring the branch looks new-born if `from` does not get supplied. New test cases for these were also added. Signed-off-by: Shawn O.
