if you’re using git-svn…
Then seriously, do yourself a favour, and add .svn to your global ignore list.
One of my colleagues committed one yesterday, so I had a fun day re-learning svndumpfilter and friends today.
Of course we can all question how this happened, I know how it happened (and so do you, if you think about it), but seriously, just do it.
I’ve put this under “amusing”, but trust me, I was not amused.
