Fix "last modified" entries not showing with nossl

On Windows with 'noshellslash', the 'dir' section would never show up due to the
unescaped backslashes in `cwd`.

escape() backslashes (if they exist) so that match() will pass properly.
Fix pathname display on Windows

glob(fname) forces `fname` to abide by the 'shellslash' setting

fnamemodify(..., ':p:~') will shorten pathnames to '~/...' if possible
