Line return in exported PO

[Olivier Le Thanh Duong]

In exported PO, Rosetta automatically use a new line when the current one get too long as does IntlTool.
The trouble is that they don't seem to use the same length for line, so they get cutted in different place.
It's a real PITA when you want to diff the two files to merge them cause it report difference even though the translation are the same.

For exemple :

Rosetta PO :
-"RECONNECT [<hôte>] [<port>] [<motdepasse>], peut être appellé juste avec /"
-"RECONNECT pour se reconnecter au serveur courant ou avec /RECONNECT ALL pour "
-"se reconnecter à tous les serveurs ouverts"

Intltool PO :
+"RECONNECT [<hôte>] [<port>] [<motdepasse>], peut être appellé juste avec "
+"/RECONNECT pour se reconnecter au serveur courant ou avec /RECONNECT ALL "
+"pour se reconnecter à tous les serveurs ouverts"

My feeling is that we should imitate gettext's behaviour to make things like diffing easier.

[Carlos Perelló Marín (carlos)]

Well, we try to do it, but there are still some situations where seems like we are not handling correctly, like this one.

Our parser does have a +1 wrap width, and that's a long standing bug (noticed while fixing #46156, basically due to usage of <= instead of <).

However, if someone wants to diff PO files, I'd advise them to msgcat them anyway.

[Данило Шеган (danilo)]

Not worth bothering with this, people can easily use msgcat to reformat PO files before diff-ing them.
