But these observations indicate several clues that do not
yet appear in the Trac ticket:

1. Occurs on Windows (I can't reproduce it in on
   Mac OS X Intel or Debian Lenny)
2. Occurs also with :r and :l, not just evaluating an expression.

Perhaps someone with with a Trac login should make note
of them.
