Avoiding expansion of mail's metacharacters

[John Gilmore]

There's an obvious and easy way to fix this problem.

Put ALL the information in the input file!

The only information that needs to go over the uucp link is "run this
program on this input file".  No argv.  The shell is happy to
deal with that, and the program is free to place any interpretation 
on the input file.

We don't need to change the already creaking uucp at this late date.
It already supports what you want to do; you just aren't using it
properly.
