There's a perl script `lc' by Paul Vixie that does this, although it
doesn't permit to use stdin.

I have posted a makefile rule to do the same thing and it should be
easy to transform this into a script.

As Jeff has pointed out, the lack of "unresolved xref" errors doesn't
necessary indicates that formatting converged.  A shure way is to keep
the output from the previous run and perform a comparison.  This has
the disadvantage that you have to have enough disk space to keep the
two output files at the same time.

This will require a major cleanup after formatting is complete so that
the new iteration would be equivalent to a fresh run.  I don't think
it worth the effort.

With a script you can control which strategy suits you best: tracking
"unresolved" messages or performing a comparison.
