The bulk update request #5673 is pending approval.
create alias curly_mane (0) -> curled_mane (134)
create implication curled_mane (134) -> mane (49419)
create implication mane_over_eye (14) -> mane (49419)
create implication mane_over_eyes (21) -> mane (49419)
Reason: Manes aren't hair (edit: for e6 tagging purposes), so tags that imply hair (like curled_hair and hair_over_eyes) shouldn't be used. That means we need mane equivalents for these tags. I'll be working on populating these more later, but might as well submit the BUR now.
Regardless of if manes are or aren't hair, curled manes are manes and manes covering one or both eyes are manes. Blue_mane and the other color tags already imply mane.
