Improve "-verbose" output

[apjanke]

Octave's test looks like this:

***** test
 [faces, vertices, fvcdata] = isocaps (x, y, z, val, iso,
                                       "zmin", "b", "verbose");
 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
***** test
 [faces, vertices, fvcdata] = isocaps (x, y, z, val, iso,
                                       "below", "v", "zmax");
 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
***** error isocaps ()
***** error isocaps (1,2,3,4,5,6,7,8,9)
***** error <parameter 'foo' not supported> isocaps (val, iso, "foo")
***** error <incorrect number of input arguments> isocaps (x, val, iso)
***** error <incorrect number of input arguments> isocaps (xx, yy, zz, val, iso, 5)
***** error <V must be a non-singleton 3-dimensional matrix>
 v2 = reshape (1:6*8, [6 8]);
 fvc = isocaps (v2, iso);
***** error <V must be a non-singleton 3-dimensional matrix>
 v3 = reshape (1:6*8, [6 1 8]);
 fvc = isocaps (v3, iso);
***** error <X must match the size of V>
 x = 1:2:24;
 fvc = isocaps (x, y, z, val, iso);

My test2 looks like this:

*****  testify.internal.BistBlock: test (index=13)
  is_test=1  is_xtest=0
  bug_id=  fixed_bug=
Code:

 [faces, vertices, fvcdata] = isocaps (x, y, z, val, iso, "xmin");
 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
  -> success=1, msg=
*****  testify.internal.BistBlock: test (index=14)
  is_test=1  is_xtest=0
  bug_id=  fixed_bug=
Code:

 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
  -> success=1, msg=
*****  testify.internal.BistBlock: test (index=15)

Code:

 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
  -> success=1, msg=
*****  testify.internal.BistBlock: test (index=16)
  is_test=1  is_xtest=0
  bug_id=  fixed_bug=
Code:

 [faces, vertices, fvcdata] = isocaps (x, y, z, val, iso,
                                       "zmin", "b", "verbose");
 assert (columns (faces), 3);
 assert (columns (vertices), 3);
 assert (columns (fvcdata), 1);
 assert (rows (vertices), rows (fvcdata));
  -> success=1, msg=

Improve its readability.

Next up, I think I need to compact the property display for BistBlock.

One more tiny tweak in https://github.com/apjanke/octave-testify/commit/67d5a85608815858917ad8812894ae5b1d9a075a: just the spacing between the "signal" symbols and the start of the text.
