Subject: [PATCH v3 9/9] ref-filter: add `sanitize` option for 'subject' atom
Date: Mon, 17 Aug 2020 18:10:22 +0000	[thread overview]
Message-ID: <1ab35e9251ab788d0334e1dc97be98dd3a2ecc1b.1597687822.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.684.v3.git.1597687822.gitgitgadget@gmail.com>

From: Hariom Verma <hariom18599@gmail.com>

Currently, subject does not take any arguments. This commit introduce
`sanitize` formatting option to 'subject' atom.

`subject:sanitize` - print sanitized subject line, suitable for a filename.

e.g.
%(subject): "the subject line"
%(subject:sanitize): "the-subject-line"
