Null response from the remote.

There are small limits on OS X:

# getconf PATH_MAX ~/
1024

On my GNU/Linux system, there is for example:

# getconf PATH_MAX ~/
4096

This are two different commands for different purposes, raised by Tramp
from the test case. I wanted to show, that the R2L property of the path
name does not seem to be the problem.

I'll try to rearrange the shell commands, let's see whether it
works. Fortunately, I can test on the remote OS X machine, again.

Best regards, Michael.
