OK - so here is a patch for you to try out.  (Well uploaded to the PR).

One thing I am particularly worried about is the heuristic I am using to 
decide when to use the \ directory separator.  At the moment it looks 
for paths starting with a drive letter eg C:.  Are there situations 
where there can be paths without this drive letter which still need the 
backslash separator ?
