For those who want to learn from source files, I would recommend
reading all the files in the very initial commit, cover to cover.

e83c5163 (Initial revision of "git", the information manager from
hell, 2005-04-07)

With only 1244 lines spread across 11 files, it is a short-read that
is completable in a single sitting for those who are reasonably
fluent in C.  It does not have any frills, but the basic data
structures to express the important concepts are already there.
