doc: add repo/ to .hgignore and .hgtags These names were disappearing in the asciidoc output and no form of escaping seems to help. Let's just add repo/ to make it explicit that they're in the repository root.

#!/bin/sh

mkdir a
cd a
hg init
echo foo > b
hg add b
hg ci -m "b" -d "1000000 0"

chmod -w .hg/store

cd ..

hg clone a b

chmod +w a/.hg/store # let test clean up

cd b
hg verify
