Hi Alan,
I have a few questions abut your change.
> * lisp/progmodes/compile.el (compilation-context-lines): Add the new value t.
> (compilation-set-window): Amend to handle compilation-context-lines being t.
> (overlay-arrow-overlay): New variable holding an overlay with before-string
> property "=>".
1- Why `overlay-arrow-overlay` without a `compilation-` prefix?
2- Why insert a prefix string (an "inserted arrow") instead of using
a "regular overwriting arrow"?
3- Why link the choice of inserted-arrow vs regular-overwriting-arrow to
compilation-context-lines specifically?

familiar with the behavior when there's no left-fringe"
