an update on direct questions without quotation marks

at paragraph 6.42, the 17th edition of the chicago manual of style notes that a direct question is sometimes included within a sentence but not enclosed in quotation marks. when such a question comes in the middle of a sentence, it is usually introduced by a comma, and (this is the new part) it begins with a capital letter. this slight departure from earlier editions of the manual recognizes that such a question is analogous to a direct quotation and can be treated similarly.

{she wondered, what am i doing?}
{legislators had to be asking themselves, can the fund be used for the current emergency, or must it remain dedicated to its original purpose?}

if the question ends before the end of the sentence, no comma is required after the question mark (see also 6.125).
