EditWordBreakProc documented the third parameter as being the number
of unicode characters in the string for richedit 2.0 and up. It turns
out that it should actually be the number of bytes in the string.
For some reason EM_POSFROMCHAR was returning 0 when the position was
equal to the end of the text, or beyond the end of the text. Instead
it should use the position at the end of the text for both these
cases. The x value was also seen to be offset by 1 according to the
tests.
Previously the shortcuts for cut, copy, paste, undo, redo, and select
all were being handled during the WM_CHAR message. These tests show
that these shortcuts should be handled with the WM_KEYDOWN message
instead.
There were some notifications that weren't sent in ME_UpdateRepaint
while redraw was disabled, so this verifies that they are not sent
with redraw disabled.
The assertion was not valid, because it neglected to take into account
the situation where a line break is forced with a MERF_ENDROW run
(caused by \line control word or pressing Shift-Enter). This means
that spaces can cause a line wrap after a forced line break as well as
after a paragraph break, so we cannot assert that it is the first row
in the paragraph.
The test for EM_GETLINE was testing to make sure the null terminating
character was written at the end of the text as long as the buffer was
long enough, and also tested to make sure that no other bytes were
written after this null terminating character. This is consistent with
Windows 2000 and up, but not for previous versions of Windows.
The table properties are streamed out at the start of the table for
non-nested tables, and at the end of the table for nested tables. The
assertion caught the fact that I didn't get the start of the table row
for nested tables before trying to stream out the properties.
The call to ME_GetTableRowStart will handle both of these cases by
getting the table row start paragraph and asserting that it is found.
This call was also the reason for removing the const qualifier on one
of the parameters.
Previously the paragraph and cell border properties were lost when
deleting the text, then undoing the deletion. This would cause tables
to lose the colour and width of the table border.
