Okay, so you want the columns to get as small as possible to fit on a
line (flexing out to fill the line if there's leftover space), and
then their contents should wrap as well.

This is easy to achieve - you need to tell the flex items to start at
the *minimum* size (taking nowrap into account), and then grow as
necessary.  Do something like this:

.column {
    flex: auto;
    width: min-content;
}

(min-content needs prefixes right now in Firefox and Webkit/Blink, so
you'll need to write "width: -wekbit-min-content; width:
-moz-min-content;".)

You *should* be able to just move the min-content keyword up into
'flex', but that's not currently supported in Chrome, at least (which
is a bug).  The above code does the same thing, since "flex: auto"
defers to the width/height property.

If you also want to enforce some reasonable minimum size (for example,
preventing a column from being less than 10em wide, even if the nowrap
parts are narrower than that), throw in a min-width as well.
