Subject: widget/reply: formatting syntax for _italics_
X-Git-Tag: v5.3~7
X-Git-Url: http://git.shiar.net/minimedit.git/commitdiff_plain/85bd24522825b832a8f30c5629b81cf90307a388?hp=df953b78c421e60f37832fa4581e5d3ca2a1bd8d

widget/reply: formatting syntax for _italics_

Single underscores for emphasis, as in mail, chat, and Markdown.
Do not cater to advanced usage like partial highlights inside words and
escapes (neither do whatsapp and slack for example); admins can use html
if really needed.
