> When using shorthands.el, autoload generation inserts a call to
> register-definition-prefixes with the shorthand prefix, instead of the
> translated print name prefix.  For example, breadcrumb-autoloads.el

> (register-definition-prefixes "breadcrumb" '("breadcrumb-"))

> This PR attempts to resolve this issue in breadcrumb.el by adding the
> correct autoload line at the bottom of the file:
