Similar question about whether we should be using ConfirmInfoBarDelegate here
instead.

[Changwan Ryu, 2014/10/14 04:04:40]

As explained elsewhere, this requires some unique design elements such as bold
file name and link for directory names (which should launch an intent). This
could not be represented by GetMessageText(). And coming up with a very generic
solution (such as what SpannableString provides) here seems hard and
unnecessary.
