>Description:
While synchronizing the copy of mtree in FreeBSD, I discovered that these three patches have not been upstreamed.

1. mtree -f file1 -f file2 does not consider type changes.
2. Add a cross reference to mtree(5), so mtree(5) <-> mtree(8).
3. fts_read: Handle error from NULL return.

Let me know if a GitHub pull request or an email with the patches are mandatory, and I'll gladly submit them.
They are all rather trivial.
Thank you.
