exchange: correctly specify url to unbundle (
issue5145)
This parameter is slightly confusingly named in wireproto, so it got
mis-specified from the start as 'push' instead of the URL to which we
are pushing. Sigh. I've got a patch for that which I'll mail
separately since it's not really appropriate for stable.
Fixes a regression in bundle2 from bundle1.
debugextension: change "testedwith" to a list (BC)
It wasn't a list since the formatter couldn't process a list. We have no
such problem now and the -T option is experimental, so we can change it.
