Csh: first character of an arg is '-': Solution

[Jak Kirman]

The test to see whether the first character of $i was '-' should have
been 

if ( x$i =~ x-* ) then          not
if ( $i =~ -* ) then

Several of the original replies used this, but I mistakenly thought it
was unnecessary, since it worked without it too.  But as was pointed out
to me, if $i has a special meaning to the shell, like -e or -x etc, it
will complain about the lack of a filename to do the existence or
executability test on.  Adding something like an 'x' or a " " before
both tests will solve this problem.

Sorry about the incorrect simplification of your answers :-)
