/**
* Ultra-simple subclass of EditTextPreference that allows the "title" to wrap
* onto multiple lines.
*
* (By default, the title of an EditTextPreference is singleLine="true"; see
* preference_holo.xml under frameworks/base. But in the "Respond via SMS"
* settings UI we want titles to be multi-line, since the customized messages
* might be fairly long, and should be able to wrap.)
*
* TODO: This is pretty cumbersome; it would be nicer for the framework to
* either allow modifying the title's attributes in XML, or at least provide
* some way from Java (given an EditTextPreference) to reach inside and get a
* handle to the "title" TextView.
*
* TODO: Also, it would reduce clutter if this could be an inner class in
* RespondViaSmsManager.java, but then there would be no way to reference the
* class from XML. That's because
* <com.android.phone.RespondViaSmsManager$MultiLineTitleEditTextPreference ... />
* isn't valid XML syntax due to the "$" character. And Preference
* elements don't have a "class" attribute, so you can't do something like
* <view class="com.android.phone.Foo$Bar"> as you can with regular views.
