Problem: "NOTE"s, inline Vim script code, and links ending in digits may not be
highlighted correctly within the :Tutor.
Solution: set an explicit value for ":syntax iskeyword" that includes digits. Do
it after ":syntax include"s, so the included syntax/sh.vim doesn't mess with the
value.
Increase screen test width so all text within the conclusion section is visible.

Problem:
Some steps in :Tutor don't work on Windows.
Solution:
Add support for `{unix:...,win:...}` format and transform the Tutor contents
depending on the platform.
