Just insurance since according to Dave Korn the grave accent notation,
ie `cmd`, is obsolete, and will probably be removed in a future version
of ksh.  Personally, I like the grave accent notation for quick command
line stuff and like the $(cmd) notation for scripts.

My hangup with ksh is that you cannot manipulate arguments to an alias.
I asked Dave Korn about adding this.  His response was that he had
considered it, however, his implementation would have to change drastically.
For example, command line size would be much more limited.
