Matt Harbison <matt_harbison@yahoo.com> [Mon, 12 Jan 2015 20:59:17 -0500] rev 23885
add: pass options via keyword args
The largefiles extensions needs to be able to pass --large, --normal and
--lfsize to subrepos via cmdutil.add() and hgsubrepo.add(). Rather than add
additional special purpose arguments, stop extracting the existing args from the
**opts passed to commands.add() and just pass them along.
