[2/44] richedit: Null pointer check missing on optional parameter

[Dylan Smith]

The function ME_FindRunInRow uses two parameters to return values by
reference, and treated these parameters as if they were optional except
for the start of the function which set *pbCaretAtEnd without checking
to see if was a NULL pointer.

I removed some redundant lines by using default values at the start of
the function.
