Nice addition, though I currently can't think of a situation where I
would actively set {curswant} to a particular column. Rather, I want my
plugins to set {curswant} when positioning the cursor (what I learned is
done by calling plain cursor(), but not plain getpos('.')). I think that
crucial distinction should be added to the help:

When 'virtualedit' is used {off} specifies the offset in
screen columns from the start of the character. E.g., a
position within a <Tab> or after the last character.
+ When {curswant} is omitted, the preferred column is set to
+ {col}, so cursor() behaves like a normal motion (unlike

Returns 0 when the position could be set, -1 otherwise.
This assumes that the patch doesn't change the previous behavior of
:call cursor(2,3) and that :call cursor([2,3,0]) behaves the same; I
haven't tested that.
