sml-modeline-vis disappears sometimes

[tkf]

When this happens, `start' variable in `sml-modeline-create' is larger than `end'.
I attached a (rather ad-hoc) patch to fix this problem.

Thanks for the bug report, tkf!

It looks to me like I have forgotten to add (length sml-begin) to the variable "end". Can you try this instead of your patch:

     (setq start (+ start (length sml-begin)))
+ (setq end (+ start (length sml-begin)))

[lborgman (lennart-borgman)]

Sorry ;-)

     (setq start (+ start (length sml-begin)))
+ (setq end (+ end (length sml-begin)))

Thank you very much for the fix! I thought it was working good, until
I found sometimes sml-modeline-vis-face disappears. In my Emacs, I can
reproduce this by doing the following:

1. open a buffer which has 3000 lines, in a window which has 42 lines
2. go to the x-th line (2720 < x < 2978)
3. hit C-l

I noticed that line 2977 is the largest line number that you don't see
the last line in the buffer.
