Subject: [bug#31036] [PATCH] gnu: Add Emacs dumb-jump

From: Sohom Bhattacharjee <[email-masked]>
Date: Tue, 3 Apr 2018 08:04:03 +0530

I added the comment because it makes it clear as to why the "v" is needed in the version. 
* gnu/packages/emacs.scm (emacs-dumb-jump): New variable.

+    "Dumb Jump is an Emacs \"jump to definition\" package with support for
+multiple programming languages that favors \"just working\" over speed or
+accuracy.  This means minimal -- and ideally zero -- configuration with
+absolutely no stored indexes (TAGS) or persistent background processes.  Dumb
+Jump performs best with The Silver Searcher `ag` or ripgrep `rg` installed.
+Dumb Jump requires at least GNU Emacs 24.3.
