SVN Log P: a partial 'git log -p' for SVN

svnlogp

#!/bin/bash
# svnlogp is a script that implements 'git log -p' for svn (partially & inefficiently): it shows all the diff's of a given filename.
#
# Due the SVN centralized architecture, it's really slow, and 'svn blame' is commonly a fair alternative.
#
# Usage: svnlogp <filename>
#
