Subject: [PATCH] contrib/git-jump: allow to configure the grep command
Message-ID: <20171109203031.25227-1-dev+git@drbeat.li>
URL: https://gitlist.dev/e/20171109203031.25227-1-dev%2Bgit%40drbeat.li

```
Add the configuration option "jump.grepCmd" that allows to configure the
command that is used to search in grep mode. This allows the users of
git-jump to use ag(1) or ack(1) as search engines.
