The CommonMark spec shows that it's not necessary to have a space
between the code fence and the language string:
https://spec.commonmark.org/0.29/#example-112
This also avoids a needless trailing space after a code fence that
does not include a language string.

Widgets have a default palette and font that is influenced by several
factors: theme, style, QApplication-wide overrides, and the parent's.
If an application sets a font or palette on a parent, then widgets
inherit those settings, no matter when they are added to the parent.
The bug is that this is not true for widgets that have an application-
wide override defined by the platform theme. For those, we need to merge
parent palette and font attributes with the theme, and this is currently
not done correctly, as the respective masks are not merged and inherited.
This change fixes this for fonts and palettes. Children are inheriting
their parent's inheritance masks, combined with the mask for the
attributes set explicitly on the parent. This makes the font and palette
resolving code correctly adopt those attributes that are set explicily,
while leaving everything else as per the theme override.
The test verifies that this works for children and grand children added
to a widget that has a palette or font set, both when themed and
unthemed. Children with own entries don't inherit from parent.
The QFont::resetFont test had to be changed, as it was testing the
wrong behavior. If the child would be added to the parent before the
font property was set, then the test would have failed. Since this
change makes sure that children inherit fonts in the same way, no
matter on when they are added to their parent, the test is now
modified to cover both cases, and ensures that they return identical
results.
[ChangeLog][QtWidgets][QWidget] Fonts and palette settings are inherited
by children from their parents even if the children have application-
wide platform theme overrides.

The markdown parser generates empty lists in some cases when a character
that can be used as a bullet is found on a line by itself.
cbEnterBlock() and cbLeaveBlock() are called symmetrically in such cases.
QStack::pop() on an empty stack triggers an assert, so push and pop need
to be done symmetrically too. But it's difficult to actually create the
list as soon as the MD_BLOCK_UL or MD_BLOCK_OL callback occurs, without
breaking the case fixed in 7224d0e427 (and
probably other cases). That's because QTextCursor::insertList() creates
a list item at the same time as it creates the list itself, and also
inherits block formatting from the previous block. We now insert empty
lists with empty items whenever the need for that is detected though,
and there's a failsafe to prevent popping in case something still goes
wrong with that logic. We aren't strict about reproducing the original
markdown when regenerating it via toMarkdown(), but it's getting closer.

Notes:
The QTextDocument table model is much simpler than the HTML table model.
It basically only has <table> and <td> support. So the HTML parser is
forced to map markup and styling to the QTextDocument model which
is not without loss.
In other words: While QTextDocument -> HTML -> QTextDocument should
preserve the QTextDocument structure, HTML -> QTextDocument -> HTML
does not preserve the HTML DOM at all.
So for now the HTML importer and writer only support border styles on
the <td> and <th> nodes. In future updates, the HTML parser might be
enhanced to map <tr> and <table> CSS styles to the cells.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.
