commit 574b3bddfcb893e52de7503f7317965397e4b514
Author: Oleh Krehel <ohwoeo...@gmail.com>
Commit: Oleh Krehel <ohwoeo...@gmail.com>
Add `aw-leading-char-style' extra-awesome custom var
* ace-window.el (aw-leading-char-style): When this is `char', the old
style is used. When this is `path', each window will display the full
path that can be used to get there. This is a great advantage, since
you don't need to scan your screen twice, instead reading two (or
more) chars at once.
(aw--lead-overlay): Update.
* avy.el (avy-traverse): Pass the whole path to WALKER, not just the
starting point.
