The default markdown implementation exhibits a bug. You can
reproduce it using the following:

M-: (when (looking-at \"\") (replace-match \"abc\"))

This will insert \"abc\" at the current point, but move point
down one line. Removing `markdown-check-change-for-wiki-link'
from `after-change-functions' fixes that."
