Correction following review. My apologies, line-width is now without leading
backslash.

The patch itself LGTM

Though sometimes I muse about whether we need NR 1.8.2 Formatting text in it's
current state at all.
Why do we explain some markup-commands explicitely and others not? They are all
listed with examples in
NR A.11 Text markup commands!

An alternative would be to improve examples in the markup-commands where needed
(as this patch does for fill-line) and, after explaining what markup is and how
to use it, simply point to NR A.11.
We already do similiar for markup-list-commands.
