indexOf returns -1 for a name that is gone and slice(0, -1) is everything but one
character, so a scope anchored on a moved name does not shrink or fail -- it
becomes the file. Renaming the end anchor took one test's body from 3,184
characters to 30,825 with the assertion still passing. The other site windowed
burstAttack at 4,000 characters over a function that runs 4,305.
bodyOf asserts the anchor and ends at the next top-level function. A missing anchor
now says which anchor and what would have happened, where the old code reported
"burstAttack still calls rollWeaponDamage" -- a claim about a call when the truth
was a claim about a name.
Also records the rest of the sweep, including the guards deliberately left alone.
