Hmph, I am not sure if this is a good move.

If we are not giving any more information than what the reader has
already learned from this page, other than "git --version" does the
same thing, we probably do not want to do this.  By seeing also that
other page, the user will not learn anything new about "git version".

If a related "git --version-something-else" is described over there
and may fill the need the reader had when visiting this page, that
is a different story, but I do not think it is the case.

This one may be a good idea, I think.

"git --version --build-options" also works and we do not want to
clutter git[1] with descriptions on suboptions of "git version".

If we are not doing so for the "--help" option in git[1], we should
do so as well.

Thanks.
