`target` in the baseline can contain line numbers

Which means baseline changes can appear from minor unrelated changes.

Although this appears to be fairly uncommon.

Egg is something like a class within a function within a class.

Start by reproducing how a baseline target containing line numbers changes after a minor unrelated edit, then trace the baseline handling described in the issue. Done means baseline changes are not triggered by unrelated line-number shifts, including the nested class/function example mentioned.
