Labels support printing multiple lines of text, but they don't relayout and
word-wrap.
Paragraphs are used by the ui.gadgets.panes for this, and basically the way
they work is you can add any gadget (but in this case a label-per-word) to
them and "word break gadgets" to represent the whitespace, so it word-wraps
properly:
500 <paragraph> 100 iota
[ " " <word-break-gadget> add-gadget ]
[ number>text <label> add-gadget ] interleave
Perhaps we should wrap this logic into a multiline-label that does the word
splitting and word wrapping for you for convenience.
