[PATCH v2 0/5] emacs: hello: convert saved-searches to plists

Sat Apr 5 22:44:44 PDT 2014


This is v2 of the series; v1 is at
id:1396733065-32602-1-git-send-email-markwalters1009 at gmail.com

I have made all the changes suggested by Austin in his review of v1. I
include the diff from v1 below.

There is now one slight oddity in the patch ordering: the
documentation for the plist form appears in patch 3 while the users
and references to that documentation appear in patch 2.

Best wishes

Mark
