Comment (by pgj):

 Replying to [comment:3 jrp]:
 > I think that an answer could be to use -E instead of -r
 (http://www.freebsd.org/cgi/man.cgi?query=sed)  although this will
 presumably not be compatible with gnu sed.

 For what it is worth, to my findings, GNU sed actually supports the
 {{{-E}}} flag, but it is not documented on its manual page.

 > Did the repvious version not work at all with BSD?

 No, it did not work with FreeBSD.  We had a solution in the Ports
 Collection for that, so I naively thought that it could be just put
 upstream, but apparently I was (quite) wrong.
