It is an excellent example that shows why "something of known length" argument needs to be rethought.

"Currently we do not need it to reimplement the canned 'tag -l' format" is an OK and sensible justification to stick to the current implementation of %(padright:N), but we'd need to think if we would want to keep this limited and strange form that applies to a single atom that comes next (ignoring any literal spans) as a private implementation detail between ref-filter and "git tag". Opening it up to end-users would not mean we cannot add a correctly operating variant of "pad this string to the right" later, but it does mean we have to maintain %(padright) in this limited form forever.

My knee-jerk reaction is that we probably should not want to expose this to the end users, and to discourage its use, perhaps name it somewhat strangely (e.g. "%(x-padright:N)" or something).
