Script for moving/renaming files/directories arbitrarily in whole git history of single branch, using perl expressions

Install into PATH e.g. $HOME/bin/ as "git-filter-mv" and chmod a+rx git-filter-mv

It works with any special characters in filenames like tabs and linefeeds. It works with empty commits.

Based on example from git-filter-branch manpage.

If you want to print debug messages, use STDERR e.g. print STDERR "File: $_\n";
