With trailing spaces in some cases, we would not get the
"no justification at end of paragraph" special case, and continue
in the code, getting the unexpected case where line_length becomes
< 0 which would lead to memory corruption because we were writing
outside our buffers. I added an assert to catch this type of bug
earlier, and I added the trailing spaces to the test for the end
of the paragraph.
The test case added is one example which would crash.

They have unexpected results in Qt 5 (the Qt::GlobalColor one works
as expected in Qt 4, but was removed in Qt 5):
QVariant v = QVariant(Qt::red);
qDebug() << v; // QVariant(int, 7)
v = Qt::red;
qDebug() << v; // QVariant(int, 7)
The correct way is to use:
QVariant v = QVariant::fromValue(QColor(Qt::red));
The deleted constructors are the ones for which there is a class
with an implicit constructor taking the enum, and that class is
a built-in metatype.
QLocale::Language and QKeySequence::StandardKey would also fit
the description, but I can't include the header for QKeySequence
as it is in QtGui, and I don't want to include the qlocale header
in qvariant.h. Putting a QLocale::Language is probably very
uncommon anyway.

to keep them consistent with positions for all other flags.
This changes the internal behavior so that attributes[0].lineBreakType now means
"break opportunity at start of the text (before the first character in the string)"
and is always assigned with HB_NoBreak to conform rule LB2
(see http://www.unicode.org/reports/tr14/#LB2).
The current implementation is based on the sample implementation from tr14
that aimed to be as simple as possible rather than to be optimal.
From now, we can use pieces of the attributes array "as is"
without having to adjust some positions. Or we can analize some long text
by chunks (e.g. paragraph by paragraph) and consume less memory.
This introduces a minor overhead that will be eliminated shortly.
