[PATCH] Enter interactive mode if no parameters are given to git-add

[Andy Parkins <andyparkins@gmail.com>]

git-add with no parameters previously adds every modified file.  This
patch instead makes git-add enter interactive mode.

This patch is against pu.

It seemed a bit nasty to add content without explicit instructions to do
so.  Instead, just drop into interactive mode, which they can easily get out
of if it was all a big accident, and additionally is quicker than typing
--interactive.
