+/**
+ * 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.
