I haven't been able to get menu selection's highlighting to misbehave.

However, consider this:

Current master:
    % _f() { a=( $'foo:hello\nworld' $'bar:lorem\nipsum' $'baz:lorem\nipsum' ); _describe descr a }
    % f <TAB>
    foo  -- lorem\nipsum
    bar  -- hello\nworld

With the patch:
    % f <TAB>
    baz  bar  -- lorem\nipsum
    foo       -- hello\nworld

Never mind the fact that current, unpatched, master escaped the newline
this time; the more important difference is that current master arranges
the display as though the description of foo is "lorem ipsum" and of bar
is "hello world", which is incorrect.
