p.25 :

"if {'Iv} and {nuq} can be pronouns, it follows that they may take
suffixes in the same manner as pronouns, and we would conclude that
the following examples are valid :

{pongDaj nuqpu'}
what was her name ?

I would only—possibly—accept this if you're asking what her name completed being. Not something one asks very often. Krankor is confusing tense with aspect.

{HoD 'Ivqanq}
who is willing to be captain ?

This seems more reasonable. I'm still not sure I accept the idea that because the pronomial question words can be used verbally means they must be able to accept verb suffixes.

{'IvvaD ghum chuS'ugh yItlhobQo'}
ask not for whom the bell tolls.."

I am far more comfortable allowing noun suffixes on the pronomial question words. I see no problem with that at all.
