T.P.RoffChar: escape `-` as `\-`.
The groff_man (7)` man page indicates that `-` characters will be
treated as typographic hyphens and are not appropriate for cases
where the output should be copy-pasteable as an ASCII
hyphen-minus character. (E.g. in command line options.)
However, until a recent update groff man did not actually do this;
it treated `-` and `\-` the same. With the new update (1.23.0)
the two are distinguished (see https://lwn.net/Articles/947941/
for background), so now it is important that pandoc escape `-`.
This reverts ee60ba5252360d2efbf9cf30197236a21a15a924.
That change was motivated by a problem with backslash-escaping
`-` in a filename for .PSPIC. That's simply a separate issue;
we shouldn't do the normal escapes in such a context. It has
been addressed in the previous commit.
