into a separate container that can overflow and side-scroll for long lines.
This effectively removes the need for all kinds of line-breaking hacks
that have been applied before and only worked when the browser was
actually able to break a word group apart somewhere.
Lines are now always rendered as-is; as a nice side effect the line numbers
are always visible, independently how far one scrolled into one direction,
so the context is always clear. If the rendering area is made smaller, the
table rendering also degrades gracefully and provides horizontal scrolling
for views that did not need them before.
The size that is occupied by the number display is now also automatically
determined by the size that is needed to render the biggest line number
in a column. Empty columns are rendered with a zero size.
Currently all this works nicely with a recent version of Chrome, Firefox
still needs some fine tuning for the vertical positioning. Other browsers
are untested as of now.
