With flowed text, end of a visual line and start of the
following visual line represent the same logical position in the
text (namely after the space char).  Currently, navigation with
left and right arrow will only ever put the cursor in the 
end-of-visual line position, meaning that it is not possible
to navigate the the start-of-visual-line with left and right.
(It is possible to click at this position, and Alpha understands
it correctly.  It is also possible to arrive at a start-of-visual-line
by going to the start-of-logicical-line and pressing downarrow a
number of times.)

I would like to suggest the convention that the two cursor 
positions should be conservative in the sense that it stays on
the line the arrow movement takes place on (as long as 
possible).  This means that if you are in visual col 1 and press
leftarrow, you end up in visual col 0 (and not at 
end-of-previous-line).  (The next leftarrow press will then of
course take you to the penultimate position of the previous
visual line.)
On the other hand, it you are in the penultimate position of a
visual line (after the last word, but before the linebreaking 
whitespace), then pressing Rightarrow should take you to the
end-of-visual-line position.
