Subject: [PATCH] Support transforming the dirname used by uniquify
By transforming the dirname, we can add additional information to use
during uniquifying. A basic one: uniquifying buffer names based on
the project name.
* lisp/progmodes/project.el (project-uniquify-dirname-transform): Add.
* lisp/uniquify.el (uniquify-dirname-transform-default)
(uniquify-dirname-transform): Add. (bug#62621)
(uniquify-rationalize-file-buffer-names, uniquify-buffer-file-name):
Use uniquify-dirname-transform.
* test/lisp/uniquify-tests.el (uniquify-home,
uniquify-project-transform): Add tests.
