spinPrint might behave strangely for longer strings

[Michael_E_Brown at Dell.com]

I think the better way would most likely be to just truncate the string we are printing.

def pad(s, n):
    return s[:n] + ' ' * (n-len(s))

Pad it to 50 or so chars. You want to send a patch?

Subject: spinPrint might behave strangely for longer strings
 

Hello,

I ran into this cosmetic issue while in the text console. At first, was not able to see this in xterm or gnome-terminal. And then I started seeing this on gnome-terminal and xterm when I resized the window. Looks like when the string output by firmwaretools.pycompat.spinPrint is larger than the column width of the terminal, it has a scrolling effect on the string as the string wraps around - clearline() tries to clear only the last line. I ended up having screen-full of the animation below:

The wrapping messes up logic. We could print the string once and cycle through the progress animation in the next line by itself.

Thanks,
Charles
