The problem with uuto and man failing if you have certain single
letter variables set is that they (uuto and man)  assume that you
have not used and exported these names for anything else.

What they do is build up a string in a loop with the
statement:

	d="$d $1"
	
in the loop.  The problem is, of course, they should set

d=

at start up rather than assume it is null.
