Sorry about that, I completely missed those.

Hmm, you're right.  I swear I tested it and it was working so I'm not
sure if I accidentally dropped them or what.

I was hoping to add a test for this use case but it ended up seeming
like a rather large task with how much the function handles coupled with
my inexperience with ERT.

I actually intended to be overly permissive in case additional options
are added in the future.  For example I was thinking it would be nice to
be able to assign a label to the custom action.

I'll defer to your pcase solution as I think my reasoning for using
pcase-let isn't particularly strong and I agree your suggestion is
cleaner.
