push: propagate --new-branch and --ssh options when pushing subrepos Up until now the all the push command options were ignored when pushing subrepos. In particular, the fact that the --new-branch command was not passed down to subrepos made it not possible to push a repo when any of its subrepos had a new branch, even if you used the --new-branch option of the push command. In addition the error message was confusing since it showed the following hint: "--new-branch hint: use 'hg push --new-branch' to create new remote branches". However using the --new_branch flag did not fix the problem, as it was ignored when pushing subrepos. This patch passes the --new-branch and --ssh flags to every subrepo that is pushed. Issues/Limitations: - All subrepo types get these flags, but only the mercurial subrepos use them. - It is no longer possible to _not_ pass down these flags to subrepos when pushing: * An alternative would be to introduce a --subrepos flag that should be used to pass down these flags to the subrepos. * If we did this, it could make sense to make the --force flag respect this new --subrepos flag as well for consistency's sake. - Matt suggested that the ssh related flags could also be passed down to subrepos during pull and clone. However it seems that it would be the "update" command that would need to get those, since subrepos are only pulled on update. In any case I'd prefer to leave that for a later patch.
