It makes more sense to have git-svnup here than catting said file in the
documentation (where we should rather point users to this directory).
I included git-svnrevert as an additional gift to the community. I will update
the documentation in a second commit later today.
git-svnrevert takes in a git hash for a commit, looks up the svn revision for
said commit and then creates the normal git revert commit message with the one
liner message, except instead of saying
Revert "<<<INSERT ONELINER HERE>>>"
This reverts commit <<<INSERT GITHASH HERE>>>
It says:
Revert "<<<INSERT ONELINER HERE>>>"
This reverts commit r<<<INSERT SVN REVISION HERE>>>
so git hashes will not escape into our svn logs (which just look unseemly).
