Your patch would still run a number of expensive operations for the
same hashes (e.g. static analysis and documentation builds). I started 
to work on a patch that moves all TravisCI logic into scripts located 
in the `ci` folder. These scripts share a `lib-travisci.sh` for common 
functions such as `skip_branch_tip_with_tag ()` executed at the
beginning of every script.

Does this sound sensible to you? I am a bit busy with non Git related 
work right now but I try to post the patch for you to review ASAP.
