[elpa] master 567570a 54/78: Fix 'at-full moving text when visual-line-mode is on

[Oleh Krehel]

branch: master
commit 567570af41c343b8a0e80308016de1be884cf9a2
Author: Oleh Krehel <address@hidden>
Commit: Oleh Krehel <address@hidden>

    Fix 'at-full moving text when visual-line-mode is on
    
    * avy.el (avy--overlay-at-full): Compute line-end-position according to
      `visual-line-mode'.
    (avy--update-offset-and-str): Add one more arg.
    
    Note that `visual-line-mode' is actually extremely slow. If you have a
    lot of candidates, you'll get a perceptible slowdown.
