[horde] Horde 4 translation pulling strings from other modules

[Luis Felipe Marzagao/Andamentos]

Hello:

After running horde-translation update --module=horde --locale=pt_BR 
strings from other modules that are also installed (imp, kronolith etc) 
were inserted in the *horde.po* file.

For example:

#: nag/templates/view/task.inc:39
#, php-format
msgid " (%s including sub-tasks)"
msgstr " (%s subtarefas incluídas)"

#: imp/folders.php:359
#: imp/mailbox.php:359
#, php-format
msgid " (Accesskey %s)"
msgstr " (Tecla de Atalho %s)"

#: ingo/filters.php:228
msgid " and"
msgstr " e"

#: imp/lib/Notification/Handler/Decorator/NewmailNotify.php:71
#, fuzzy
msgid " and "
msgstr " em "

#: lib/Block/Weatherdotcom.php:240
#: lib/Block/Weatherdotcom.php:343
#: lib/Block/Weatherdotcom.php:389
msgid " at "
msgstr " em "

Is this the expected behaviour or am I doing something wrong?

Thanks
Luis Felipe
