If in the first place the reason for wanting to use tt in a
report chapter title is that the underscore without tt does
not properly match the other characters, then I think it
would be better to emulate the underscore with a rule, as,
for example, \protect\rule[-0.2ex]{0.5em}{0.15ex}.  For this
it's relevant whether or not the tt would be used, say, only
to "highlight" the name of a string variable inside a longer
chapter title.

IMO setting a report chapter title in tt looks bad; it might
be more tolerable in a section title.
