Bonus: typo in regressions.js, downcase 'Command-line' in cmdline.txt
(as it's not speaking about mode, hope thesnowdog will agree)

Mostly typos/omissions/markup errors, more remarkable e. g. changing
'b' to 'B' in tutorial reflecting a change from 1.2.
Also uncommented [macros] section in asciidoc.conf (is that right?).
