The status list isn't rendered as list, but rather as normal paragraph,
because there is missing blank line between "Status:" line and the list.
Fix the issue by adding the blank line separator.

dm writecache: make writeback pause configurable
Commit 95b88f4d71cb953e02206be3c757083601391a0f ("dm writecache: pause
writeback if cache full and origin being written directly") introduced a
code that pauses cache flushing if we are issuing writes directly to the
origin.
Improve that initial commit by making the timeout code configurable
(via the option "pause_writeback"). Also change the default from 1s to
3s because it performed better.
