convert/bzr: fix test of divergent nested renames for bzr 1.x

54c0517c0fe8 introduced a new block in test-convert-bzr-directories.t
which produces a slightly different output with older bzr versions.
Tested with bzr 1.5 on Debian lenny.

"lfconvert" includes a newline at the end of the standin files.

add another largefile to the new largefiles repo

round-trip: converting back to a normal (non-largefiles) repo with
"lfconvert --to-normal" should give the same as ../bigfile-repo
  $ cd largefiles-repo
  $ hg lfconvert --to-normal . ../normal-repo
  initializing destination ../normal-repo
  $ cd ../normal-repo

# Hmmm: the changeset ID for rev 5 is different from the original
# normal repo (../bigfile-repo), because the changelog filelist
# differs between the two incarnations of rev 5: this repo includes
# 'large' in the list, but ../bigfile-repo does not. Since rev 5
# removes 'large' relative to the first parent in both repos, it seems
# to me that lfconvert is doing a *better* job than
# "hg remove" + "hg merge" + "hg commit".
