Why? The documentation states:

  -b, --escape               print C-style escapes for nongraphic characters

but - looks like a graphical character to me, so it doesn't need an escape.

I don't see a problem here, so I'm marking this as not a bug; however,
feel free to followup with more details, such as better justification
for why - should be treated as a nongraphic character.
