What's more this doesn't even work for me (probably because I tend to clone without `.git` suffix)

```
alex@ajh-mint ~/src/sprout $ echo $(git config --get remote.origin.url|sed -e 's#^\([^:]*\):\([^/]*\)\([^.]*\)[.]git#http://\1/\2\3/tree/#')$(git rev-parse HEAD)
git@github.com:Metaswitch/sproutaa1620cd45cb21a34521e6a3fa46702c27781767
alex@ajh-mint ~/src/sprout $ git config --get remote.origin.url
git@github.com:Metaswitch/sprout
```
