REST api "repos/{owner}/{repo}/compare/{basehead}" cannot compare between commits

[Zarklord]

Description

The documentation for that specific rest API describes the {basehead} as the following:

compare two branches or commits

but, in reality, it's only capable of comparing between two branches/tags, because the source code explicitly checks if the base is a branch or a tag and if the head is a branch of a tag which prevents you from comparing commits like the api's description implies you can, and that you can compare between commits on the web interface

(also as an aside, but the expected format of {basehead} isn't stated anywhere, nor is there an example for you to infer it)
