Your process is the one I would be inclined to use too. I do try to avoid
cherry-picking though. This is probably because cherry-pick changes could
cause annoying merge conflict problems in Bazaar. Is this less of a problem
in Git?

I'm mostly basing this on the article
They make what seem like good arguments for this approach.

To be honest though, I haven't gone back and looked at history in depth
often enough that the supposed benefits outweigh the extra overhead. I feel
like the main benefit is the ease of porting the bugfix to various
branches. On the other hand, if you have good branching practices, it
probably should be quite easy to port the change from one existing branch
to another.

The history is still contained at the file level, and putting an english

This is the sort of thought process I am interested in. I agree that good
commit messages are really important. In the case where I make a new branch
for a bugfix, I'd be inclined to include a custom merge message explaining
the bugfix.

Agreed. I don't have a problem with administration overhead when I know
that I will thank myself later. The trick is figuring out which things are
necessary or not. I think it probably varies depending on the project. I
know I'd be less organized on a personal pet project than on something that
will be shared, or that I'll be expected to meet deadlines on at some
