It seems as if the autoscrolling options can be set based on whether
WS_VSCROLL or WS_HSCROLL styles are used to create the window, but this
is done differently between version 1.0 and 3.0 of the richedit control.
I noticed this indirectly before because wordwrap is initially set only
if the auto-horizontal scrolling is initially enabled.

Same remark about the W-calls.
