Install the templates where they can be found by hgweb.py
This ought to use package_data but that doesn't exist in Python 2.3.
So we do a hack of install_data and use glob.
This also adds templatepath() to hgweb.py which finds the templates
relative to hgweb.py's location.
set -ex
export EDITOR=true
rm -rf test branch
mkdir test
cd test
echo foo>foo
hg init
hg addremove
hg commit
hg verify
cd ..
cp -a test branch
cd branch
echo bar>>foo
hg commit
cd ../test
hg merge ../branch
hg verify
