Hmm. This way forces you to write
if $dry; then
echo do something
else
do something
fi
in many current usage cases or use yet another variable again, whereas
with my patch you can just do
$dry do something
but still can do
test -n "$dry" && dosometing_which_is_not_echoed
or even
test "$dry" && ...
and the semantics should still be rather obvious to the reader.
Cheers,
Ralf
