Remove leading/trailing whitespace from commit messages when importing from Subversion?

I was wondering if it's possible to removing leading and trailing whitespace (tabs, newlines, spaces) from commit messages when importing from Subversion via git-svn.

I've got a repository with tens of thousands of commits, and not all of the messages are entered... sanely. I need to know whether it is possible to clean these up when transfering the repository to Git.

Thanks.

Try "git filter-branch --msg-filter your-filter-command".

Thank you, after-the-fact works fine too. :)

If anyone else searches the archives and wonders how I did it, this sed command is it: sed -e "s/^[ \t]*//;s/[ \t]*$//;/^$/d"

Unix rules!
