Yeah, I noticed this but couldn't see how to fix it at the time.

While this will fix the man pages, it breaks the various other versions
of the manual (HTML, PDF, RTF, etc).

The docbook-to-man man page suggests using the SGML entity name for
characters which cause a problem like this (so use \ instead of a
literal backslash here) but when I tried that before it just came out as
\ in the manual (but it did fix the man page).

But I've just realised that I can define \ myself at the top
of manual.sgml and then it works in both cases.  Hurrah!
