  Log Message:
  -----------
  use doctest ELLIPSIS for bandwidth() values to avoid ULP failures

bandwidth() gets its value from a scipy.optimize.root_scalar bisection,
so the last digit or two of the repr differs across scipy/BLAS builds.
The full-precision literals matched locally but failed on GitHub.

Truncate to ~14 significant digits with # doctest: +ELLIPSIS.  This
keeps the examples verified (unlike +SKIP, used elsewhere in the repo
for platform-dependent output), and trim_doctest_flags (on by default)
strips the flag comment from the rendered HTML.

Also applied to the G1*G2 example, which has the same origin and had
not failed yet.

Verified with "make doctest" in doc/: 728 tests, 0 failures.
