Version: 29.0.50
Severity: wishlist
Tags: patch

There are project commands and keys corresponding
to the most useful buffer commands:

  C-x k (kill-buffer)      - C-x p k (project-kill-buffers)
  C-x b (switch-to-buffer) - C-x p b (project-switch-to-buffer)

What is still missing is a command to list project buffers:

  C-x C-b (list-buffers)   - C-x p C-b (project-list-buffers)

project-kill-buffers already shows a list of project buffers,
but only as a part of confirmation for killing buffers.

Here is a patch that adds the missing command.  Its argument
has exactly the same meaning as in 'list-buffers'.
