tests/test-hgweb-no-request-uri

Fix income/pull with bundle and -R (issue 820).

Uses ui.setconfig() to tell bundlerepo where the main repo is. This is
needed for when the --repository option is used.

Adds tests to test-bundle and a new test script
test-mq-pull-from-bundle, which plays out the situation that initially
made me detect this bug

(hg -R .hg/patches pull ../bundle.hg).

#!/bin/sh
# This tests if hgweb and hgwebdir still work if the REQUEST_URI variable is
# no longer passed with the request. Instead, SCRIPT_NAME and PATH_INFO
# should be used from d74fc8dec2b4 onward to route the request.

mkdir repo
cd repo
hg init
echo foo > bar
hg add bar
hg commit -m "test" -d "0 0" -u "Testing"
hg tip
