I can reproduce that even with the default setting for font-lock-doc-face.
I'm also getting a highligted "g" (in the isearch face) overlayed over the
"o" in comint-prompt-regexp of ielm-get-old-input. This is the same place
where the cursor used to be at the other occurrence of lookup. It seems
like some redisplay bug related to the cursor (independent of
blink-cursor-mode).
Andreas.
