Subject: Switch to strong and em implementation based on Tim Pope's.
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/e3bbd8b78aa50235dbb87a515f0fb0384621447d?ds=inline

Switch to strong and em implementation based on Tim Pope's.

Seems to fix some problems with mine. Changed so *'s and _'s inside words don't
start emphasis, which is not canonical but everyone seems to like better.
