How to remove old (out commented) msgid from po files?
问题
在我的Python代码中，我将_("Every 30 minutes") 修改为_("Every {n} minutes").format(...)。通过使用xgettext更新pot（po模板）的工作效果很好。旧的msgid完全消失在该文件中，新的msgid出现。
但是，接下来通过使用msgmerge --update基于pot更新我的po文件让我感到困惑。旧的msgid并没有消失，而只是被注释掉了。
#~ msgid "Every 30 minutes"
我能否在某种程度上影响这种行为，防止msgmerge创建它们？
英文:
I'm quite new to the GNU gettext tools. So please feel free to correct me if I use the wrong terms.
In my Python code I modified _("Every 30 minutes") to _("Every {n} minutes").format(...).
Updating the pot (po-template) via xgettext worked well. The old msgid totally disapeared in that file and the new msgid appeared.
But then updating my po files based on the pot (using msgmerge --update) do confuse me. The old msgid do not disappear but is just out commented.
#~ msgid "Every 30 minutes"
Can I influence that behaviour somehow and prevent msgmerge from creating them?

我认为 msgfmt 没有这样的选项，但所有过时的条目 - 这就是它们的称呼 - 都位于文件的末尾，您可以轻松使用文本编辑器将它们删除。
过时的条目保留在 .po 文件中，因为它们随时可以重新激活，当涉及到的消息再次出现在您的源代码中时。同样，如果新字符串类似于过时的字符串，它们可以用作模糊条目的基础。出于这个原因，大多数人保留了过时的条目。
英文:
I think there is no such option to msgfmt but all obsolete entries - that is what they are called - are at the end of the file and you can easily remove them with a text editor.
Obsolete are kept in the .po file because they can always be re-activated, when the message in question re-appears in your sources. Likewise, they can be used as the base for a fuzzy entry if a new string resembles an obsolete one. Most people keep the obsolete entries for that reason.
