When you run a script, it executes in a subshell. That subshell has its own environment space, so things like $PWD (or any set variable) will be lost. To paraphrase: "What happens in a subshell stays in a subshell."
Therefore, you canot use a script to change the current working directory of your login shell. You could define an alias, or a function, which would run in the current shell. But the script can't do it.

edit-patch
EDIT-PATCH(1) General Commands Manual EDIT-PATCH(1)
NAME
edit-patch, add-patch - tool for preparing patches for Debian source packages
SYNOPSIS
edit-patch path/to/patch
add-patch path/to/patch
DESCRIPTION
edit-patch is a wrapper script around the Quilt, CDBS, and dpatch patch systems. It simplifies the process of preparing and editing patches
to Debian source packages and allows the user to not have to be concerned with which patch system is in use. Run from inside the root
directory of the source package, edit-patch can be used to edit existing patches located in debian/patches.
It can also be used to incorporate new patches. If pointed at a patch not already present, it will copy the patch to debian/patches in the
correct format for the patch system in use. Next, the patch is applied and a subshell is opened in order to edit the patch. Typing exit
or pressing Ctrl-d will close the subshell and launch an editor to record the debian/changelog entry.
edit-patch is integrated with the Bazaar and Git version control systems. The patch will be automatically added to the tree, and the
debian/changelog entry will be used as the commit message.
If no patch system is present, the patch is applied inline, and a copy is stored in debian/patches-applied.
add-patch is the non-interactive version of edit-patch. The patch will be incorporated but no editor or subshell will be spawned.
