Different translations for a single string in debian installer

[Jens Seidel <jensseidel@users.sf.net>]

Hi,

the Debian Installer uses the string "none" in various packages but only
one translation can be provided for all these:

#: ../partman-basicfilesystems.templates:172 ../base-installer.templates:101
#: ../partman-lvm.templates:19
msgid "none"

Now I noticed that the grammar requires slightly different translations
dependant on the usage. Any way to reach this?
