Same i18ngrep comment as in the earlier patch (i.e., we can use grep
here).

Hmm. So I see now why you wanted to go with the strbuf in the earlier
patch. This does still feel awkward, though. You check "is it allowed"
in an earlier function, we get "nope, it's not allowed", and now we have
to reimplement the check here. That seems like a maintenance burden.

I think a more natural flow would be either:

  - the "is it allowed" functions calls immediately into the function
    that sends the error and dies (this might need a conditional if
    there's a caller who doesn't want to die; I didn't check)

or

  - on failure it populates an error buffer itself, which the caller can
    then pass along as it sees fit
