/* This test attempts to show that WM_SETTEXT on a riched32 control does not
attempt to modify the text that is pasted into the control, and should
return it as is. In particular, \r\r\n is NOT converted, unlike riched20.
Currently, builtin riched32 mangles solitary \r or \n when not part of
a \r\n pair.
For riched32, the rules for breaking lines seem to be the following:
- \r\n is one line break. This is the normal case.
- \r{0,N}\n is one line break. In particular, \n by itself is a line break.
- \n{1,N} are that many line breaks.
- \r with text or other characters (except \n) past it, is a line break. That
is, a run of \r{N} without a terminating \n is considered N line breaks
- \r at the end of the text is NOT a line break. This differs from riched20,
where \r at the end of the text is a proper line break.
