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

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.
