When searching for root line num, stop at the end of the file. (#1015)

Browse Source 
* When searching for root line num, stop at the end of the file.

When using the following NERDTreeStatusLine, Vim would lock up and not
work anymore. The problem was that when trying to find the root line
number, the loop was continuing past the end of the file, looping
"forever". The fix was to simply stop at the end of the file.

let g:NERDTreeStatusline = "%{exists('g:NERDTreeFileNode')&&" .
      \ "has_key(g:NERDTreeFileNode.GetSelected(),'path')?" .
      \ "g:NERDTreeFileNode.GetSelected().path.getLastPathComponent(0):''}"

* Update change log.
