From fb1c016cb5ec5263b24c9210c26f8e6f6cfd0942 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Sat, 14 Jan 2012 16:46:15 +0200 Subject: [PATCH] cli: slightly refactor "notmuch reply" address scanning functions Slightly refactor "notmuch reply" recipient and user from address scanning functions in preparation for reply-to-sender feature. Add support for not adding recipients at all (just scan for user from address), and returning the number of recipients added. No externally visible functional changes.
