Minor improvements on the svnsafeup function:
- use last line of diffstat as header
- add 2nd level folds to diff sections, folding each file's diff
- require "y" to continue to `svn up`
If the svn plugin is used, svn info (repo name and wether the repo is dirty) is displayed in the prompt like with git. Just lke with git, the colors can be manipulated with variables (see awesomepanda theme for example).
