elpa-diminish 0.45-1 (amd64 binary) in ubuntu bionic

 Minor modes each put a word on the mode line to signify that they're active.
 This can cause other displays, such as % of file that point is at, to run off
 the right side of the screen. For some minor modes, such as
 mouse-avoidance-mode, the display is a waste of space, since users typically
 set the mode in their .emacs and never change it. For other modes, such as
 jiggle-mode, it's a waste because there's already a visual indication of
 whether the mode is in effect.
 .
 A diminished mode is a minor mode that has had its mode line display
 diminished, usually to nothing, although diminishing to a shorter word or a
 single letter is also supported. This package implements diminished modes.
