commit.txt: clarify how --author argument is used

commit --author was added by 146ea06 (git commit --author=$name: look $name up in existing commits), but its documentation was sorely lacking compared to its excellent commit message. This commit tries to improve the documentation. Signed-off-by: Jay Soffian <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>
