The "Published (xx)" string should use ngettext(), since it can take different values. It would not impact english, but would in French for instance :
Publié (0)
Publié (1)
Publiés (2)
Right now we are pretty much forced to use "Publié(s) (xx)".
Same for these I guess:
Scheduled (%s)
Pending Review (%s)
Draft (%s)
Private (%s)
These could also be useful:
Already pinged: -> Already pinged: %s
Done! <strong>%1$s</strong> categories imported.
Done! <strong>%1$s</strong> users imported.
imported %s
ignored %s
There are currently %1$s comments identified as spam.
...and maybe more :)
Thanks for changing these in time for 2.5 :)
