Ah, much is now explained.  You were looking at an old version.  I had
in fact already fixed the subdirectories bug (I've updated my
regression test to check) and have full support for branchy repos,
preserving tags and branch heads.

Yours emits no D ops for files removed after a particular snapshot.

Apparently you missed the part where I byte-stuffed the message content.
It's a technique used in a lot of old-school Internet protocols, notably
in SMTP.

There's a certain elegance to that, but it would be hard to generate by hand.

Remember that a major use case for this tool is making repositories 
from projects whose back history exists only as tarballs.  So, let's
say you have the following:

foo-1.1.tar.gz
foo-1.2.tar.gz
foo-1.3.tar.gz

What you're going to do before weaving is drop the untarred file trees
in a 'foo' scratch directory, then hand-craft a log file that might
look a bit like this:

-----------------------------------
commit 1
directory foo-1.1

Release 1.1 of project foo
.
commit 2
directory foo-1.2

..This is an example of a byte-stuffed line.

Release 1.2 of project foo
.
commit 3
directory foo-1.3

Release 1.3 of project foo
.
-----------------------------------

The main objective of the logfile design is to make hand-crafting 
these easy.
