"Automerge" refers to the server-side merging of directory changes which
we perform before upon commit. I'll illustrate how it conflicts with
signing directory content.

Repository is at rev 1000. You and I both have working dirs at rev

I add file foo/bar. I sign the file foo/bar, the directory foo, and the
root directory, and commit, producing rev 1001.

Without first updating, you add file foo/baz. You sign the file
foo/baz, the directory foo (which does not contain foo/bar), and the
root directory, and commit, producing rev 1002. But no one has signed
the contents of directory foo as it appears in rev 1002; what you signed
was a version of the directory foo which never actually made revision

If we didn't have automerge, then your attempt to commit would fail, and
then you would update, generate correct signatures, and commit. But
developers would find the system rather less convenient to use.
