The effect specifies whether underlining is turned on, while bUnderlineType
indicates the type of underlining.

The test that succeeded from this change was as a result of allowing the
end of the character format change be specified using NULL as the rest
of the text. Before, the end paragraph run at the end of the text was
not being set for this case, when all the text was supposed to have its
character format changed.
This prevents some needless searching for the start of the paragraph
from a run stored in a cursor. Usually a pointer to the paragraph is
already available when the cursor is set anyway.
When finding an adjacent paragraph, the next_para and prev_para pointers
should be used because they are direct pointers, a constant time
operation. Instead I found some places in the code that searched through
the general linked list to get to an adjacent paragraph, which is a linear
time operation, depending on the number of rows and runs in between
paragraphs.
Previously a count of the carraige returns and line feeds were stored
for end of paragraph runs, and a paragraph sign was stored as the actual
string. This was causing many special cases where the length of the
run needed to be determined differently if the run was or wasn't an
end of paragraph run.
There wasn't any use for storing the paragraph sign unless some drawing
code gets commented out to allow the end paragraphs to be shown,
therefore I changed the code to store the actual string that gets
retrieved by WM_GETTEXT.
The methods in ITextHost are mostly thin wrappers around functions that
take a handle to a window as their first parameter. This patch just
uses the wrapper functions provided by ITextHost instead of using the
functions that require a handle to a window that the editor might now
have (for windowless richedit controls).
EM_GETPARAFORMAT previously would overwrite the cbSize field with the
size of PARAFORMAT2, would read past the end of the struct, and might
indicate that PARAFORMAT2 fields are valid using the mask regardless
of the value of cbSize.
If a EM_SETPARAFORMAT message is sent to the richedit control with bits
in the dwMask field that correspond to PARAFORMAT2 fields, then these
fields should be ignored. Instead data was copied from outside of the
structure.
Previously the WM_NCCREATE was handled by the as if it was always for
later versions, then the window proc for version 1.0 would make
appropriate changes afterwards. Instead both versions should call the
same function (e.g. ME_MakeEditor) and provide the value for
bEmulateVersion10 to make the code clearer.
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.
The values returned by EM_SETPARAFORMAT and EM_GETPARAFORMAT previously
indicated an error, and the included tests shows that Windows behaves as
documented.
I created a function to set the default paragraph format to ensure
consistency when this is done. This initial paragraph format is also
now more consistent with native richedit controls. The dwMask value
always appears to have the same value when retrieved from the native
richedit controls, so all the mask values are now initialized when the
PARAFORMAT2 structure is created.
The PARAFORMAT structure has a bit in wEffects to indicate whether the
paragraph is a table or not, so this should be used instead of a private
bTable value, since this structure can be retrieved with EM_GETPARAFORMAT.
