Support for git diffs

[Jasha10]

In git diffs, there are sometimes lines that look like this:

index f80b65d..c8f438a 100644
--- a/tests/test_signature_parsing.py
+++ b/tests/test_signature_parsing.py
@@ -317,7 +317,7 @@ def expects_int(x: int) -> int:

fpp picks up on the path a/tests/test_signature_parsing.py, but that path has a prefix a/ that is not desired (i.e. tests/test_signature_parsing.py would be prefered).

I wonder: what is the best way for me (as a user) to handle this use-case? I.e. I would like to perform some processing of the selected path(s), e.g. using sed, before passing the paths to a command or opening with an editor.
