QtC misindents in qmessagebox.cpp

Didn't notice something like this in 14.0.2, but I wasn't working in qmessagebox.cpp, either.

Given: qmessagebox.cpp open in e.g. qtbase/0a567a7f926f433cbd1294131aac0e80dcfd7943.

When: placing the cursor after the opening { of QMessageBoxPrivate::setVisible(bool) and hitting return.

Then: the cursor is indented by 2 spaces.

Expected: 4 spaces.

This is not a setting issue. Opening qinputdialog.cpp from the same checkout and placing the cursor after the opening { of QInputDialogPrivate::setVisible(bool) and hitting return correctly indents by 4 spaces.
