This is some shell scripting portability fixes.

1. modish is changed to a directory.

  On Solaris 7 and 4.4BSD, sticky bit for non-directories can be set
  only by root.  If an usual user attempt to do it, Solaris 7 simply
  ignores the bit and 4.4BSD --- I tested on FreeBSD 2.2.8, NetBSD
  1.4.1 and BSD/OS 3.0 --- causes EFTYPE.

2. The format of `df' is different on Solaris 7.

Z:akr@is27e1u11% df /
/                  (/dev/dsk/c0t0d0s0 ): 1221764 blocks   316009 files
Z:akr@is27e1u11% 

3. mknod cannot be used for making a pipe on 4.4BSD.

Z:akr@ape% mknod pipe p 
usage: mknod name [b | c] major minor
zsh: exit 1     mknod pipe p
Z:akr@ape% 

mkfifo should be used instead.  mknod on NetBSD 1.4.1 supports above
usage, though.
