[PATCH consfigurator] WRITE-REMOTE-FILE: accept more spaces in output from "ls -nd".

[David Bremner]

This is needed to work with the "ls -nd" output from busybox, used in OpenWRT
among other places.  For consistency this also changes "..?" after the mode to
"[ ]+".  I verified that at least on FreeBSD, "ls -nd" does indeed uses spaces
after the mode, while GNU coreutils "ls -nd" uses a single space.
