Uh, oh, this is a bug in groff itself due to bad interaction between
tbl and eqn.  Thanks for the report!

The problem is that UTP uses the backtick character (`) for short eqn
formulae.  However, code emitted by tbl contains this:

  .tm1 "warning: file `\n[.F]', around line \n[.c]:
  .tm1 "  table wider than line width

Obviously the single backquote character in .tm1 ruins everything
afterwards...

Two possible quick fixes:

. Add the `nowarn' parameter to all global tbl options, this is,
  change for example

    .TS
    center,box

  to

    .TS
    center,box,nowarn

. Use e.g. `$' instead of the backtick for all short eqn formulae.


Actually, this is quite a serious problem IMHO: How can I guarantee
that tbl and eqn harmonize?  Maybe ignore .tm and .tm1 lines
completely?

PS: There are more problems while compiling UTP which I will analyze
    later.
