It seems that there is something strange with wordwrapped labels
with some fonts. Apparently one part of QT thinks it is showing
a single line and sizes the line vertically accordingly. Another
part thinks there isn't enough space and wraps the label. The
result is two lines in a single line space, cutting off parts of
the lines. It doesn't happen with every font, nor with every
"long" label.
This change works around the problem by setting the maximum
display width and telling QT to respect that width.
While here I implemented an arbitrary minimum label length so
that there is a better chance that the field edit boxes line up.
