No matter what you do, I think EXIT STATUS section should consistently
come near the end of the document, immediately before SEE ALSO, which is
where people who know how manual pages are written expect to find it.

Prose is much easier to read as long as it is brief enough, than two-item
enumeration:

> EXIT STATUS
> -----------
> Zero status:      There is a different between the index file and HEAD.
> Non-zero status:  There is nothing to commit by running `git commit`. 

whose use of "Zero status" makes it look doubly funny (traditionally
manual pages do not seem to spell out exit status 0 as "zero", but
"non-zero" is Ok).

Avoid talking about only one side of the condition if you can without
being too verbose.

        The command exits with status 0 if there is something to commit by
        running `git commit` with corresponding arguments, and non-zero
        otherwise.
