Two invocations of "git reset" not mentioned

[dcecile]

At http://gitref.org/basic/#reset the author is talking about the complexity of git reset and says, "I'll just tell you the three specific invocations of it..." In the reference manual, only git reset HEAD is used; the remaining two of three invocations are missing.

I think this should either link to or re-use some Three Trees content from @schacon.
