I noticed that "command-line-usage" has print width of 80 by default, and it does not increase when the text would fit in the terminal window. Also, the descpition of --lang flag shifts layout the most, so I replaced list of languages with LANG, since LANG is already defined in synopsis. Additionally, I added --src-lang to synopsis
