Each time I added some strings to a Django project, I run "django-admin.py makemessages -all" to generate .PO files for all locales.
The problem is even I only added 5 news strings, the makemessages command will mark 50 strings as fuzzy in .PO files which brings a lot of extra work for our locale maintainers.
This also makes the entire i18n unusable before they manually revise those fuzzy strings.
