Grab the svn HEAD git commit number?

Question

In regular git I can run

git rev-parse HEAD

to get the git HEAD revision number. How would I get the svn HEAD revision number instead?

I know I can manually grab it by looking at the git log for the last commit with a git-svn-id. Also, looking through the manual for log pretty-format there's a way to get the ref name (%d) which in the case of the HEAD svn commit shows up as git-svn.

Thanks.

It's a bit of a hack and I welcome improvements but here's what I've got so far.

I've added an alias to my git config:

svnhead = log --grep=git-svn --pretty=format:'%h' -n 1

now I can call

git svnhead 

to return the short git commit hash and I can pass it in to

git rebase -i $(git svnhead)

for example to interactive rebase everything from the svn head commit.

I recently realized this can be done using rev-parse:

git rev-parse master

if your master branch tracks the SVN repo, or

git rev-parse git-svn
