;; Known bugs
|
|
;; ==========
|
|
|
|
;; When edititing a symlink and *both* the symlink and its target
|
|
;; are bzr-versioned, `vc-bzr` presently runs `bzr status` on the
|
|
;; symlink, thereby not detecting whether the actual contents
|
|
;; (that is, the target contents) are changed.
|
|
;; See https://bugs.launchpad.net/vc-bzr/+bug/116607
|
|
|
|
;; For an up-to-date list of bugs, please see:
