it's to remove the first level of directory as in my example the paths 
had been

--- orgcopy/orig    2024-08-02 14:22:59.937683379 +0200
+++ revisedcopy/orig    2024-08-02 10:17:25.108469758 +0200

so -p1 would make it same as:
--- orig    2024-08-02 14:22:59.937683379 +0200
+++ orig    2024-08-02 10:17:25.108469758 +0200

Say you had had:

--- src1/dir/orig    2024-08-02 14:22:59.937683379 +0200
+++ src2/dir/orig    2024-08-02 10:17:25.108469758 +0200

and you are in the src1/dir applying the patch, you would like to remove 
two levels and use -p2, but if you had been in src1 then you would just 
use -p1.

I hope that was understandable...
