Comment 3 for bug 1835320

> "add update-rtp-for-mu-debug" doesn't really explain anything from a user's perspective.

How about something like "Fix debug function"? I would have just uploaded but I didn't want to change text attributed to you without your permission (nor do I want to remove your attribution).

To be clear, I'm not asking that you use my exact wording or remove what you've already got there - I'm just requesting that text that users have a chance of understanding is present.
