[kramdown-users] Prettier command-line options

[Eric Sunshine]

The present behavior of kramdown is to display and accept options of the 
form --foo_bar and --no-foo_bar, which is rather ugly, more difficult to 
type than the equivalent options --foo-bar and --no-foo-bar, and 
inconsistent with most other command-line programs. Perhaps it would be 
a good idea for kramdown to transform --foo_bar to --foo-bar when 
emitted as help and vice-versa when parsed as an argument. (For backward 
compatibility, it also can continue accepting --foo_bar.)
