Yeah, you should use the full hash. For temporary references, like during
a code review, you can use the first "several" digits of the hash. For a
project of FreeBSD's size, "several" is probably 11-13. But in permanent
contexts, like commit logs, you should use the full hash. When somebody
views the commit on a platform like Github, Github will automatically turn
it into a hyperlink, and display only the first "several" digits.
