git a/xyz or b/xyz

[Fabrice Creuzot <code@xxxxxxxxxxx>]

Hello

When we are reading a "git diff", all paths are prefixed with "a/" and 
"b/". Example:

diff --git a/xyz
index 4aa4b5230..1c2b8b69e 100644
--- a/xyz
+++ b/xyz
@@ -1,7 +1,7 @@


With my terminal, I double click on the path to select the full path for 
copy.

Then, when I paste: "git log a/xyz",
 git says: unknown revision or path not in the working tree

Ok, I need to remove the "a/" or "b/".
But, is git can understand that "a/xyz" is "xyz" because "a/xyz" does 
not exist?

Thanks
