Subject: [PATCH] Use regex for trimming file:// destinations

A problem with cut was causing:

  $ DEST="file:///media/user/data"
  $ TMPDEST=$(echo "${DEST}" | cut -c 6-)
  $ echo $TMPDEST
  ///media/user/data

The fix uses a regex instead so that we trim away things correctly. It also seems somewhat more
readable.
