Previous argument inserted at the wrong point when writing a subshell

[timbertson]

Normal operation:

$ echo one
$ echo [alt-up]
# command line is now "echo one"

But if you're writing a subshell, the argument gets put in the wrong place:

$ echo one
$ echo (echo [alt-up]
# command line is now "echo one(echo", and the cursor is over the "("

Good find!
