commands: automatically word-wrap cmdline options
Some of the descriptions of command line options were getting quite
long, and when translated they are likely to grow even longer. This
word-wraps them at 70 characters, just like the help texts.
We could have opted to wrap them at the terminal width instead, but I
think it looks better to have them be consistent with the help texts.
