This may be the result of moving over to goption, but zenity has lost it's
feature of being able to add new lines in the msg dialog.

For example -

zenity --info --no-wrap --text="<span foreground=\"blue\"
background=\"orange\">label</span>"

works nicely

but

zenity --info --no-wrap --text="<span foreground=\"blue\"
background=\"orange\">label</span> \n vote for me!"

doesn't. Not sure why this is happening, because gtk_label_set_markup seems to
get the correct string.
