This puts a box around arbitrary text.  It also happens to set up \.
for leaders, but that's a separate issue.  The key is using \bgroup
and \egroup.

Also, if you want to allow arbitrary text, you *must* take a width a
a parameter, or use a hard-coded one (possibly some smidge less than
\textwidth). . . .

\newenvironment {leaderbox*} [1]
  {
  \begingroup
  \par \noindent \hfill
  \setbox0=\vbox \bgroup \hsize #1 \@parboxrestore
  \let \. = \leaderfill
  }
  {
  \egroup
  \fbox{\box0}
  \hfill \penalty0 \par
  \endgroup
  }
