fixed translation

[lslezak]

Note: #{foo} does not work properly in translated messages, the substitution is done before translating the string, gettext then won't find any translation for it...

No, it still does not look good (which is not lslezak's fault).
If we look at the presets we see that :name and :help are initialized with the N_() methods, so I think there may be a translation call missing somewhere.
