As I sit here blaming code to find the original source of a line of code I’m beginning to think that svn needs a new improved version of blame called spelunk it would work something like this:

$ svn help spelunk

spelunk (curse, showup, show): Output the content of specified files or URLs with the original revision and author information in-line ignoring white space changes and following movement of code between files.

Yes – I know I am dreaming 😉
