[Tails-l10n] translations using poedit

Hi,

currently I'm using poedit 1.5.4 (backported) for the translations.
Usually, it removes some of the flags and changes the header, for example:
----%<----%<----%<----%<----%<----%<----%<----%<----%<----%<----
diff --git a/wiki/src/doc/encryption_and_privacy/gpgapplet.de.po

Is there a way to change this behaviour so that there are minimal
changes? (I already set the name, email address and such)
On the other hand, there are some commits that "Unfuzzy strings." or
"Unfuzzy translation.", so maybe this is ok/should be done anyways?

Furthermore, if I save a file I get errors like "header field
`Project-Id-Version` still has the initial default value". This is
annoying but poedit saves the file correctly, so it's more a usability
thing.

At the moment, I reset the changes poedit does during interactive
add/checkout when doing the final review before commit.
Is this necessary, or is it ok to have changed file headers?

Is there a way to have automatic line breaks, let's say after 72 characters.

Maybe I'll try vim with gettext plugin intead of poedit...
