Vista - how to get rid of line wrapping in powershell

PS C:\Temp> '-' * 200 >a.txt
halfway correctly generates a line of 200 - and incorrectly adds an
additional newline
C:\Temp>powershell -command '-' * 200 >a.txt
wraps the line into two lines.

How can I get rid of these behaviors

You should probably check your results again. I can't reproduce this on my
machine.
I assume that your second command is actually:
PS> powershell -command "'-' * 200 >b.txt"

You can use the .NET StreamWriter to avoid any additional newlines:

$streamWriter = new-object System.IO.StreamWriter('C:\Temp\a.txt')
$streamWriter.Write('-' * 200)
$streamWriter.Close()
$streamWriter.Dispose()

It's a usability trade-off, right? If you had to manually provide a newline
for all output:

"Hi there`n"
"Here's another line`n"
"And here's another`n"

Then that would kind of suck. However I have been there, especially when
outputting to a file, when you really don't want that last newline. It
would be nice to have some control over that behavior. Perhaps something
like:

'-' * 200 | out-file -NoNewline a.txt

actually the command is
c:\temp> powershell ./somescript >b.txt
I wasn't clear enough:
I ran powershell from a .cmd batch file (together with some other
non-powershell scripts)
As soon as the '>' is handled by cmd I get the wrapping
So in a way you solved my problem:
c:\temp> powershell "./somescript >b.txt"
does not do any wrapping
