commit e5a839cbb6b72cfc8f09d388523f8c74e8829b5b
Author: Drew Adams <address@hidden>
Commit: Stefan Monnier <address@hidden>
* zones.el: Silence compiler warnings
(hlt-last-face, repeat-message-function)
(repeat-previous-repeated-command): Declare.
(zz-fringe-for-narrowing): Remove spurious * in docstring.
(zz-izones): Remove unused var `newval`.
(zz-zones-complement): Remove unused arg `buffer`.
(zz-zone-union): Don't forget to use `buffer`.
(zz-add-zone, zz-delete-zone, zz-unite-zones, narrow-to-defun):
Follow the _ convention for ignored vars.
(zz-markerize): Remove unused var `buf`.
(zz-string-match-p): Define in a way that the bytecompiler understands.
(zz-narrow-repeat, zz-select-region-repeat): Remove unused arg `arg`.
