Interesting question - I just tested and, if you use, say `" /foo/bar"`, jsch expands that to an absolute path of `/home/ftptest/ /foo/bar` - it doesn't fail, and we create a folder hierarchy `\ /foo/bar` in the user's home.

This is probably not what someone would intend but I wonder if we should disallow it - it's doing exactly what they asked for. In the case of `"/foo/bar" where /foo doesn't exist, jsch crashes with a String index out of bounds exception.

But, I'll use `hasText()` if you prefer.
