Re: [libvirt] [PATCH] virsh: Ensure the parents of the readline history path exists

Instead of changing the existed virFileMakePath to accept mode
argument and modifying a pile of its uses, this patch introduces
virFileMakePathWithMode, and use it instead of mkdir() to create
the readline history dir.

Does this always do the right thing? Remember, 'mkdir -p a/b/c' has the
ability to create parent directories 'a' and 'a/b' with a different mode
than the final directory 'a/b/c'; it is often the case that you want the
parent directories to have more permissions than the final child.

But if we are happy with all intermediate directories being created mode
0755 instead of the default of 0777 from the original virFileMakePath,
then this patch makes sense.
ACK.
