When recalling memory of a monster, the leftmost character of the description is used for indentation. However, that character is not written; it's just skipped. This means that the underlying characters (from e.g. the player status on the left of the main map view) blurs into the monster description text, like this:
The White worm mass ('w')/('w'): [(r)ecall, ESC]
You have killed at least 18 of these creatures.
MIt is a large slimy mass of worms.
NThis natural creature is normally found on dungeon level 1, and moves extremely erratically, and
Lslowly. A kill of this creature is worth 0.40 points for a 5th level character. It breeds
Nexplosively. It can crawl on you to poison.
