checkout problem for trailing spaces at file name

[Huluvu424242]

Hello, there was an checkout problem at window if you try to checkout your project from scratch via git clone.

Cause: the file Array/LongStrWithoutRepeat.js has 3 trailing spaces in the file name!

$ git clone git@github.com:Huluvu424242/JavaScript.git
