def description
  <<-EOF
Show the given ticket attachment.  The patch will be highlighted in a manner
If the filename is omitted, show a list of attachments for the ticket.

If the literal word "branches" is given, a list of all remote heads is output,
followed by the branches that refer to them.  A literal "rebased" also shows
branches that appear to be rebased attachments.  These rebased branches will be
shown in brackets.

Attachments can be downloaded by redirecting to a file.  The following example
shows how one might download all patches for a given ticket:

  for patch in $(git-trac show 123); do
    git-trac show $patch > $(basename $patch)
  done
