civicrm-setup and backward slashes in file paths on windows don't play nice together

Is the end plan for a typical production install to run civicrm-setup live on the target server as opposed to the current installer? If so then the backwards slashes will cause some problems on windows. This is similar to #1572 (closed)

If I make the naive change below I can at least get past the part where it loads tables, but then elsewhere it still has backwards slashes. And my civicrm.settings.php ends up with a mix of forward and backward in the same variable sometimes, although you can always fix civicrm.settings.php easily enough manually after.

Otherwise it seems quite nice and potentially very versatile.
