'-' vs '\-' in TH (man(7))

Hi Branden,

I just noticed that the Linux man-pages use '-' in TH.  That's
surprising to me, as Michael was careful to use '\-' correctly.

In the documentation, I couldn't find anything that says TH
should be different than anywhere else, and so I'd expect he
would have used it there.

$ grep -rn '^\.TH [^ ]*-' man* | wc -l
30
$ grep -rn '^\.TH [^ ]*\\-' man* | wc -l
0

Was it just an oversight, or are there any obscure reasons to do
that?

Cheers,
Alex
