[Development] qtbase 5.7.0 changelog help

[Thiago Macieira]

Please help with the following entries. They contain text that is either 
incorrect, hard to understand or not clear enough for users of Qt that are not 
familiar with the internals. For any entry listed here that doesn't get a 
reply from someone, it will be deleted from the changelog.

 - QWheelEvent::phase() now returns 0 rather than Qt::ScrollUpdate when the
   wheel event comes from an actual non-emulated mouse wheel and the
   environment variable QT_ENABLE_MOUSE_WHEEL_TRACKING is set. In Qt 5.6,
   this is required to enable the fix for QTBUG-50199.
[What's this about 5.6?]

   * [QTBUG-53338] Fixed crash when comparing a initialized QAuthenticator
     with an uninitialized QAuthenticator.
[What do you mean with uninitialized?]

[Android section]
 - Allow the user to choose how much from Android theme is extracted.
[how? A little more detail, please. And wrong tense]

[moc section]
 - [QTBUG-53441] Fixed crash on file ending with \\\r
[clarification needed on just what the file couldn't end in]
