I think it's extremely funny. You thought I was going to say something
about making guns illegal, didn't you?

Creating the files and then hard-linking them
1. requires more free space (because the files are temporarily not
2. is slower (for one thing, general scripts don't know about Bazaar's
3. is less convenient

We're not talking about a just branch here. The patch adds support to
checkout too, and I've got support ready for cbranch also. You want
merge? I can do merge, too. Revert would just be a pain, though.
But more importantly, it's not a special case, it's a recommended
workflow: feature branches. You branch (or cbranch), commit, maybe
merge, and submit. I think we should promote this workflow, so I think
we should try to make it very convenient to use. Just because we can do
it the inconvenient way doesn't mean we shouldn't do it the convenient
way. People should feel free to branch at the drop of a hat.
