Any reason for forcing the newline in these messages?

[Marijn Kruisselbrink, 2012/09/11 18:03:38]

Because the code that uses these potentially concatenates several of these
strings for multiple extensions/apps, and they should all end up on their own
line. Maybe it would indeed be better to change that code to add the newline
there instead of having the newline in all of the strings that can be used
there.

[sky, 2012/09/11 18:16:46]

Yes, I think that would be less error prone.

[Marijn Kruisselbrink, 2012/09/13 17:31:24]

Done.
