Make earlygetopt return a list of all option values, use the last value. This fixes: "hg -R" showing a useful error instead of traceback "hg -R foo --repository bar" using bar instead of foo And provides a way for other users of earlygetopt to accept more than one value.

#!/bin/sh

hg init
touch a
hg add a
hg ci -m "a" -d "1000000 0"

echo 123 > b
hg add b
hg diff --nodates

hg diff --nodates -r tip

echo foo > a
hg diff --nodates

hg diff -r ""
hg diff -r tip -r ""

true
