Exercise 9 - Viewing history

Make a commit with a multi line commit message (leaving an empty line after the first line)
View that commit in the log
```
 git log -1
```
View the full commit log
```
 git log
```

If the log fills your whole terminal, press q to exit

View a shortened version of the commit log
```
 git log --oneline
```
Pick a commit hash from the log
View the commit log from the chosen commit backward
```
 git log --oneline <commit_hash>
```
How much of the commit hash do you need to specify? Hint, run git help log 88cf350 renamed for style - seems if we just show these characters, we get a message
How can you show just the last three commit messages?
