The bulk update request #12323 has been approved by @evazion.
rename foot_against_wall -> foot_kabedon
create alias foot_on_wall -> foot_against_wall
create alias feet_on_wall -> feet_against_wall
Foot against wall is currently used for kabedons done with a foot (leg), but the name is fairly ambiguous. Generic food against wall is impossible to search (usually a standing on one leg situation, post #4731468), expect a very small feet on wall tag. Which is in plural for some reason.
Foot kabedon could imply foot against wall, but there’s also cicada block (meme) involving both feet, not sure how to deal with that one?
