I just had a quick look at what it'd take to update xwax and noticed
that lintian gives me the following warning:

---
 This manual page seems to contain a hyphen where a minus sign was
 intended. By default, "-" chars are interpreted as hyphens (U+2010) by
 groff, not as minus signs (U+002D). Since options to programs use minus
 signs (U+002D), this means for example in UTF-8 locales that you cannot
 cut and paste options, nor search for them easily. The Debian groff
 package currently forces "-" to be interpreted as a minus sign due to
 the number of manual pages with this problem, but this is a
 Debian-specific modification and hopefully eventually can be removed.

 "-" must be escaped ("\-") to be interpreted as minus. If you really
 intend a hyphen (normally you don't), write it as "\(hy" to emphasise
 that fact. See groff(7) and especially groff_char(7) for details, and
 also the thread starting with
 http://lists.debian.org/debian-devel/2003/debian-devel-20030/msg01481.html
