multios screen width issue

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

    $ aptitude why "grep" >&2 >! /_output _file

If I do the above in a narrowish terminal, the first line of output (" 
i   hibernate ...") is forced to wrap due to being rather long, but all 
subsequent lines are double spaced.  If the terminal is wider such that 
the first line does not wrap, then neither are there double spaces, OR, 
if I use:

    $ aptitude why "grep"

... the wrapping is always correct, even if the terminal is narrow -- 
the first line wraps but the subsequent lines are single spaced.  This 
is interesting because the issue of screen wrapping seems like it would 
not be effected by the addition of redirection to a file, since in that 
case line length issues would seem irrelevant, yet it interferes with 
proper line wrapping on the screen.
