Hi Thomas,

For HTTP URLs (skipping the last awk and sed commands for clarity).

curl https://alioth.debian.org/anonscm/git/openstack/ceilometer.git/HEAD

The approach with ls-remote is not guaranteed to give the default branch, if
there are one or more additional branches with the same hash.  With this
limitation in mind, it can still be simplified as follows.

git ls-remote https://alioth.debian.org/anonscm/git/openstack/ceilometer.git | sort | sort  | grep -i HEAD | sed -n 2p 

Have a nice Sunday,
