Revised quoting of command line arguments for WIN32

* We only need to quote an argument if it contains whitespace.

* There's no point in quoting ? or * because Windows still expands
  them. Anyhow, if the command line comes from a BusyBox shell it will
  usually have handled the globbing, so we should turn off Windows
  globbing for any wildcard that has made it through the shell without
  expansion. This means that BusyBox commands run from cmd.exe won't do
  wildcard expansion, though.

* Backslashes only need to be doubled if they occur immediately before
  double quotes.

* Double quotes need to be escaped with a backslash.
