See attached patch.

This may need to go into 3.0.

Fixing sprintf placeholders

This looks like an honest mistake - surprised no one caught it yet!

I guess these strings have to be manually translated so us changing them doesn't directly affect translators?

As far as I understand, the non gettexted strings are handled automatically by the build system that is used by the various locale.wordpress.org sites.

(You tell the build system which WP tag/branch to use with which locale tag/branch. It then puts together the package, making the replacements of non-gettexted strings automatically and saving the changed files as UTF-8 without a BOM.)

So, on the one hand, translations will not be affected.

On the other hand, translations will still have a string that gives no information.

Looks like I screwed this up in [12732]. Committing.
