[PATCH] Convert update-index references in docs to add.

["Shawn O. Pearce" <spearce@spearce.org>]

Since `git add` is the approved porcelain for an end-user to invoke
when they want to manipulate the index, porcelain documentation
should steer the user to this command rather than the pure plumbing
update-index.

Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

 Maybe this isn't the best change to make.  I dunno.  I think it is
 cleaner to keep the user looking at add instead of update-index,
 but what do I know.  :-)
