Subject: [PATCH v4] log: add log.follow config option
Date: Wed, 8 Jul 2015 13:42:01 -0400 [thread overview]
Message-ID: <1436377321-8495-1-git-send-email-dturner@twopensource.com> (raw)
This version uses tweak, and also includes Matthieu Moy's suggested
whitespace fix.
---
Many users prefer to always use --follow with logs. Rather than
aliasing the command, an option might be more convenient for some.
Junio C Hamano <gitster@pobox.com> suggested using the tweak
functionality for this, which is much nicer than what I had before.
