Full context was:
--tree-filter <command>::
This is the filter for rewriting the tree and its contents.
The argument is evaluated in shell with the working
directory set to the root of the checked out tree. The new tree
is then used as-is (new files are auto-added, disappeared files
are auto-removed - neither .gitignore files nor any other ignore
rules *HAVE ANY EFFECT*!).
+
In case the <command> is a shell script, provide an absolute path.
An example: --tree-filter 'sh /path/to/filter.sh'

I don't know.

The problem was that I was trying to use a sell script for athe
manipulation:
cd <gir repo>
git filter-branch --tree-filter "sh ../filter.sh" HEAD
Which didn't. It needed absolute path:
cd <gir repo>
git filter-branch --tree-filter "sh $(pwd)/filter.sh" HEAD
And that didn't work quit either. Script was run, but paths weren't no
longer relative to the "working dir" I was cd'd to:
rm file \
dir/file \
dir/file \
..
So, someone please explain how the paths should be expressed in shell
script and we'll improve the docs.
