These are things that were (IMO) missed in 5afac1ed.  I found them using:

    git grep -E '(plain|msg|msg2|warning|error|die) "[^"]*\$'

I went a little above-and-beyond for escaping strings for the error
messages in db-functions' arch_repo_add and arch_repo_remove.  The
code should explain itself, but I wanted to point it out, as it's more than
the usual "slap %s in there, and move the ${...} to the right".
