[Help-gnu-arch] Help composing a sample session

I'm trying to write a sample Arch session for a survey paper I'm
working on, and failing.

Here's my sequence of commands;

  # Clear all arch state
  rm -fr {arch} {archives} ~/.arch-params/ .arch-ids foo.txt [email protected]

  tla my-id "Eric S. Raymond <[email protected]>"
  mkdir {archives}
  tla make-archive [email protected] {archives}/2007-example
  tla my-default-archive [email protected]
  tla archives
  tla whereis-archive [email protected]
  tla archive-setup example--trunk--0.1
  tla categories
  tla branches example
  tla versions example--trunk
  tla init-tree example--trunk--0.1
  echo "This is a one-liner file." >foo.txt
  tla add foo.txt
  tla make-log

The last command echoes this:

[email protected]

I then edit the log file, 

The problem cones when I try to commit:

commit: tree has no patch log entries for version
    tree: /home/esr/public_html/writings/version-control
    version:[email protected]/example--trunk--0.1

This log message is actually missing its trailing \n, so my next
shell prompt is run on to it.

What am I doing wrong here?
