`missing' needs patch for Ultrix4.4

[Jim Meyering]

I finally have an account on an Ultrix system
and have tracked down a couple problems.
The first was that `missing --run :' would fail like this:
(the other is in autoconf)

  $ sh missing --run :
  sh: º: not found
  WARNING: `:' is needed, and you do not seem to have it handy on your

This patch seems to preserve the semantics and avoids the problem:

        * missing (--run): Use `eval' to run `"$@"'.  Otherwise, Ultrix4.4's
        /bin/sh fails and outputs garbage.

If anyone sees a problem with this, let me know.
