> When some option has a really long description (at least 3 lines), it wraps incorrectly.
See attached picture, it's a total mess.
> The problem is, you have default width set to 74 characters. But when you are printing
the second line of the description, you forget to count also the preceding white space into
the 74 characters. Therefore the second line wraps into a third line. After all 74 characters
are printed, you start again on fourth line with a correct preceding white space. And over
and over again.
> This fix should be really easy. Just count the whitespace.
