;; Notes on mark and region: to get a consistent behaviour whether Transient
|

|
;; mode is on or off, check `mark-active'. It will work as expected if

|
;; transient. If not, it will always be true as soon as the mark has been set
|
|
|
|
;; once; so you need to make sure the mark is set as you want beforehand (e.g.
|
|
|
|
;; whole buffer, single line...). This is the behaviour of `sort-lines'.
