Fix some edge strings; particularly revision editing

Summary:
These didn't get translated quite right:

  - We need to use `$total_count` because some languages have different words for 1, 2-3, and 4+ things (for example). So the strings might translate as:
    - alincoln added a reviewer-one ...
    - alincoln added reviewers-few ...
    - alincoln added reviewers-many ...
  - That is, while English has only "reviewer" and "reviewers", other languages have more plural forms, and "reviewer", "reviewers-few" and "reviewers-many" may be completely different words.
  - In English, because we know we always have 2+ in this branch and the only special word is for 1, we can just drop this.
  - Anyway, the %4$s stuff is counting assuming that $total_count is included in the string, so these were a off by one.
  - See also D11160.

There a probably a couple more of these, but they should be easy enough to hunt down as they crop up.

Test Plan: Saw nice strings instead of empty strings, or invalid strings (after D11160).
