vi !-2$

$ vi test.txt
$ echo  svn commit
svn commit
$ vi !-2$
vi test.txt

man bash
search for HISTORY EXPANSION, all caps.

> And in the general case, what gives me the Nth argument from the command
> M steps back in my history?

!-M:N

Example:

$ vi a b c d
4 files to edit
$ echo test
test
$ vi !-2:3
vi c

Hope this helps
