Actually, I was suggesting that symlink_wsl was doing the wrong thing in case 
the user used an uppercase drive letter.  WSL doesn't recognize /mnt/C, so I 
don't think symlink_wsl should convert /cygdrive/C to /mnt/C.

The latter seems like the safest solution, rather than risk breaking some other 
use case.
