There is indeed a single command: svn revert
As far as I can tell from the docs, 'svn revert' merely puts the files back
to the state they were last in in the repo. This would be equivalent to
'git reset'.
What I'm talking about is committing a set of changes, then later,
possibly many commits later, issuing another command that undoes the
earlier commit.
For example. I remove a block of code and commit the change. Later, we
decide we need the block of code back:
git revert commit-id
using the ID for the change that removed the block of code will create a
new commit that puts the block of code back in.
I think this can be done with 'svn merge', but you'd have to figure out
what files are involved and which versions to specify by yourself.
This kind of thing is somewhat of a chicken-and-egg problem. People don't
think of backing out older changes because their VCS doesn't do it easily,
and the VCSes don't do it because they ask users, and the users don't think
they need it. There are a lot of very useful things that can be easily
done once you have all of your history around.
