Crash due to typo introduced by Weblate made me realize I wasn't running
the script that ensures translated strings have the same set of format
specifiers as the English -- which might not be strictly necessary, but
it's safer to enforce it for now. Moved a few remaining %s to %1$s style
while at it.
I modified existing translated strings, adding the new clause. Not doing
that would cause the existing strings to be stripped because they'd no
longer have the matching set of format specifiers.
