Refactor try_print_trimmed_def_path.

Browse Source 
Inverting the condition lets us merge the two `Ok(false)` paths. I also
find the inverted condition easier to read: "all the things that must be
true for trimming to occur", instead of "any of the things that must be
true for trimming to not occur".
