add --options to debugcomplete and change bash_completion to use it make debugcomplete print one item per line (this is not needed for the bash_completion script, but should be easier to use in other scripts)

#!/bin/sh

hg init a
echo a > a/a
hg --cwd a ci -A -m a
hg clone a b
echo b > b/b
hg --cwd b ci -A -m b
chmod 100 a/.hg
hg --cwd b push ../a
chmod 700 a/.hg
