Almost all messages in up2date include hard-coded line breaks ("\n"). These are
bad both for localization and accessibility. Below is the rationale:

---
Avoid hard-coded line breaks whenever possible in text that is to be shown with
variable width fonts, if you can use a toolkit that allows for automatic line
wrapping, such as GTK+. In other words, don't do it like this:

   message = _("GFoo is an excellent frobnicator\n"
               "application that supports many\n"
               "different frobnicators. It was\n"
               "written by F. Foo and B. Bar\n"
               "with help from B. Baz.");
   

Instead, use automatic line wrapping and make the message have no line breaks:

   message = _("GFoo is an excellent frobnicator "
               "application that supports many "
               "different frobnicators. It was "
               "written by F. Foo and B. Bar "
               "with help from B. Baz.");
   

The reasons for this is that making the lines have the appropriate width with
some variable-width font that is different from the one used when editing is not
only a difficult task for the developer, it's also a very difficult task for all
translators. Also, the danger of line breaks "moving around" when the developer
changes the hard-coded wrapping (and thus all translations needing updates) is
eliminated when line breaks are removed.

Automatic line wrapping is also very useful for users that need accessibility
and other users that want to use different fonts or bigger fonts.

Please consider using automatic line wrapping where possible.
