Description of problem:
  Autofs passes an incorrect directive to mount when making a bind mount through
a program map.

Version-Release number of selected component (if applicable):
  autofs-4.1.3-187

How reproducible:
  Every time.

Steps to Reproduce:
1.  Create an auto.master file with the line: "/u program:/etc/auto.test"
2.  Create a 755 file "auto.test" with these contents:
    #!/bin/bash
    #All directories under /u are bind mounts to /tmp
    echo "/ -fstype=none,rw,bind :/tmp"
3.  Run "ls /u/testdir"
  
Actual results:
  No such directory testdir.

Expected results:
  /u/testdir should be the same as /tmp

Additional info:
  After some troubleshooting, I found that mount is getting passed this: "-t
none -o bind,rw :/tmp /u/testdir"

  The colon is wrong, and the mount fails. The same test with FC 5's autofs does
not result in mount being passed the colon, and everything works correctly. I
solved this problem on our mailserver by creating a wrapper around mount that
parses the input. Another of our systems programmers found that if the line from
auto.test is changed to: echo "-fstype=none,rw,bind :/tmp", mount is passed the
correct value, though this appears to be a non-standard format. (Note that you
cannot remove the colon from auto.test, because it is there to escape the
leading slash in the argument, which is otherwise expanded.)
