From bab633d3ac87167dc214094f9d340655885a01b1 Mon Sep 17 00:00:00 2001 From: David Bremner Date: Thu, 30 Sep 2021 14:17:48 -0300 Subject: [PATCH] config: ignore leading/trailing spaces in ';'-delimited lists In [1] Ciprian observed that it was easy for users to mistakenly introduce leading and trailing space to new.tags when editing a notmuch config file. This commit strips spaces on either side of the ';' delimiter when splitting. In principle it would be possible to support tags (or other config values) with leading or trailing spaces by processing '\s' escapes in the input string. Currently such processing is not done.
