Error in Window Closing

[KSR-Yasuda]

It shows an error in window closing by x key in TabManager window:

function <SNR>156_ManDelete の処理中にエラーが検出されました:
行   22:
E16: 無効な範囲です:  3winc w

It says unavialable range of 3.

Do below to repro:

1. Set let g:tabman_side = 'right' in .vimrc
2. Run vim
   • 1 window exists
3. Open new window
   • 2 window exists
4. Open TabManager window
   • 3 window exists
5. Close a window by x hotkey in TabManager window
   • Then, it closes a window, and it has 2 windows including TabManager
   • After that, it tries to close window 3, but range over
     • It was old TabManager window number in g:tabman_side = 'right' case

I think this line is unnecessary.
Why you do this line?

[KSR-Yasuda]

I misunderstood: that line was not window closing,
but going back to the window where it had been, was it?

So, it should decriment curwin
if s:ManSelect()-ed (or closing) window is before curwin, huh?
(Also, if curwin is the closing window, it should move to another.)

It is the case with g:tabman_side = 'right',
as it will likely to close an window before TabManager.

I'll check and fix it later.

Fixed.

Besides window, closing tab before current tab had the same problem.

Fixed: g:tabman_side = 'right' and closing the tabman window itself.
