Nice!

Patch looks good to me. Intuitively, it looks like a more logical
way to perform things too. And with the new SEARCH_SYMBOL searching
mechanism coming, I can see us being able later to to avoid the "<...>"
wrapping too.

Just in case, I tested that patch against our testsuite, and I can
confirm it fixes the issue without introducing regressions :).

Thanks for having looked into this, Pedro. I will focus my attention
on creating the branch, do a review or two, and then continue analyzing
my testsuite report.
