Line 484 reads:
			( "$A{shell}" || "/bin/sh -c" ),
Change this to:
			( $A{shell} || "/bin/sh -c" ),

There is another instance of the same on line 492. Change those and it
should be silent. Untested, YMMV, etc.

Note: my debugging here is based entirely on reading the code, I've
literally not tested it. The problem is that undefined string
interpolation in strict mode causes a warning. The warning isn't
actually a problem and dirvish should work fine without you changing the
above (conversely, if it doesn't currently work fine, it won't after
you do the above).

Good luck :)
