**************** INPUT ****************
Bookloupe understands simple underlining, for example, a _bd_ word as
well as old-school underlining, for example, _a_pr_word_.

It also understands partial underlining, as in l'_Adthima_, Abag_ae_l,
_ph_antasm, and even _ph_antasi_z_e.

While warnings about missing spaces around underscores are generally
suppressed, partial underlining with_an odd number of un_der_scor_es
will still be warned about.

Then just a couple of special cases we need to check for: first _simple_
underlining with an underscore at the end of the line and a solitary _
should both be handled correctly.
